What the Net seems to be doing is chipping away my capacity for concentration and contemplation. Whether I’m online or not, my mind now expects to take in information the way the Net distributes it: in a swiftly moving stream of particles. Once I was a scuba diver in the sea of words. Now I zip along the surface like a guy on a Jet Ski.

In the United States, of the ten million certified scuba divers, it is likely that only a few hundred dive deep for shipwrecks. To those few, it is not a matter of if they will taste death, only of whether they'll swallow.
Robert Kurson (Shadow Divers)
There is a major difference between a scuba diver and a drowning man. One is in control of his experiences, the other is in over his head.
Laren Grey Umphlett (The Power of Perception)
My heart felt like a balloon that was filling too full, and I panicked. I might get the bends, the way scuba divers did when they surfaced too fast.
Janet Fitch (White Oleander)

Love is like Atlantis, OK? And I’m just a humble scuba diver searching for treasure that I can exchange for sexual favors.

Are you an experienced scuba diver? Great, shed your gear, take a deep breath and become a one-hundred-foot free diver. Are you a badass triathlete? Cool, learn how to rock climb. Are you enjoying a wildly successful career? Wonderful, learn a new language or skill. Get a second degree. Always be willing to embrace ignorance and become the dumb fuck in the classroom again, because that is the only way to expand your body of knowledge and body of work. It’s the only way to expand your mind.
David Goggins (Can't Hurt Me: Master Your Mind and Defy the Odds)
Something, most certainly, happens to a diver’s emotions underwater. It is not merely a side effect of the pleasing, vaguely erotic sensation of water pressure on the body. Nor is it alone the peculiar sense of weightlessness, which permits a diver to hang motionless in open water, observing sea life large as whales around him; not the ability of a diver, descending in that condition, to slowly tumble and rotate in all three spatial planes. It is not the exhilaration from disorientation that comes when one’s point of view starts to lose its “lefts” and “down” and gains instead something else, a unique perception that grows out of the ease of movement in three dimensions. It is not from the diminishment of gravity to a force little more emphatic than a suggestion. It is not solely exposure to an unfamiliar intensity of life. It is not a state of rapture with the bottomless blue world beneath one’s feet…it is some complicated mix of these emotions, together with the constant proximity of real terror.
Barry Lopez (About This Life: Journeys on the Threshold of Memory)

in scuba diving, going down and staying down are not the difficult bits, (a brick can do that.) Coming up again is the part that requires skill.
Simon Pridmore (Scuba Confidential - An Insider's Guide to Becoming a Better Diver)
IN a heartbeat, the diver is reborn, swallowed into another reality, transformed from a shambling monster into a being of weightless grace. Is this what happens to the spirit at death when it flies up to heaven?
Sy Montgomery (The Soul of an Octopus: A Surprising Exploration into the Wonder of Consciousness)
Scuba divers can make it to three hundred feet breathing mixed gases, but it takes years of training and is a logistical nightmare. The danger isn’t going down—although that certainly is dangerous—it’s coming back up. For a scuba diver, a one-hour plunge at two hundred feet breathing regular compressed air would require a ten-hour ascent to purge the deadly levels of nitrogen gas in the blood that accumulate on the way down. A three-hundred-foot ascent on compressed air would most likely kill you.
James Nestor (Deep: Freediving, Renegade Science, and What the Ocean Tells Us About Ourselves)
snuck into the vacant copilot’s room next to our victim, carrying a bucket with the sea cucumber. I crept through the room, being careful not to make any noise. I removed the sea cucumber and slid it into our victim’s toilet, being careful not to splash any water. The sea cucumber looked like a world record, giant turd. It was jet black, about fourteen inches long and thick around as a coke can. Neither of our pilots was a scuba diver and I guessed they would never suspect the giant turd was really a sea creature. The humongous turd impersonator lay motionless in the bottom of the toilet bowl, leaking a faint reddish dye. When they discovered the state of the toilet the pilots began a heated argument, blaming each other for not flushing the disgusting mound of excrement. This was a serious breach of etiquette for an officer and gentleman. The hapless pilots finally tried flushing and the toilet backed up and flooded the bathroom. They had to summon a plumber who immediately recognized the turd for what it was, a sea cucumber, and said it must have somehow crawled up through the pipes. Neither pilot ever guessed they were the victims of a practical joke. The prank was flawless and I still have the picture of the cucumber in their toilet.
William F. Sine (Guardian Angel: Life and Death Adventures with Pararescue, the World's Most Powerful Commando Rescue Force)
A great diving scene. Worth the read just for that: “Randy! You have the best eyes for bubbles. Find my missing diver.” Paul leaned over the boat and yelled at the people waiting in the water. “Hey! Where’s . . .” He examined the faces. It didn’t take long to figure out who was missing. His heart spiraled to his feet. “Oh, no, no, no!” He didn’t hesitate to jump to action. He yelled out orders as he put his gear on in record time. “Get back on the boat. Now!” “I see bubbles! Over there, ‘bout fifteen meters,” Randy called before anyone had a chance to do anything. Paul stood on the back of the boat, all geared up and holding an extra tank with a regulator already attached. He looked to see where Randy pointed and took a giant stride into the water. He didn’t bother to surface before starting the fastest descent he’d ever made.

Downdraughts and Upwellings Just the mention of a downcurrent is enough to inspire fear in many divers as they visualize themselves getting caught by an irresistible force that drags them into the abyss with no opportunity for escape. The natural response when confronted with a situation like this where you feel out of control is to panic but there is no need. Normally, downdraughts or downcurrents are localized phenomena that occur along reef walls: think of them as waterfalls in the sea. When you encounter one, the first thing to do is get out of the flow by moving closer in to the wall so that the contours offer you shelter. Once out of the stream, relax, exhale, take a few deep full breaths, check your air supply, depth and decompression status, look around you and plan. Look to see where the big fish are hiding or if there is a place where the sea whips are not waving around. It is not a good idea to fight a downcurrent. It is a struggle you cannot win. The oft-quoted tactic of inflating your BCD to counteract its efforts to carry you down is potentially dangerous as the current might suddenly release you from its hold and you will find yourself on a runaway ascent to the surface, which will do you much more harm than the current could do. Unless you have spotted a place further along the wall that seems calm, usually the best advice is to swim laterally out away from the reef towards the blue. If you find yourself being carried a little deeper initially, stay calm and keep swimming, you will emerge from the pull of the downcurrent before long or its effect will weaken and allow you to begin your ascent and return to the wall. Think of upwellings as reverse down currents. The same advice applies. First move into the wall out of the flow, relax, think, observe and act calmly.

That’s one of the problems with the way I’m wired. I don’t trust people to accept who I am in process. I’m the kind of person who wants to present my most honest, authentic self to the world—so I hide backstage and rehearse honest and authentic lines until the curtain opens. I only say this because the same personality trait that made me a good writer also made me terrible at relationships. You can only hide backstage for so long. To have an intimate relationship, you have to show people who you really are. I’d gotten good at reeling in a woman and then bowing to say, “Thanks, you’ve been a great audience,” right about the time I had to let her know who I really was. I hardly knew who I really was myself, much less how to be fully known. WHEN BETSY ARRIVED IN ASHEVILLE, I’D HARDLY talked to another human being in weeks. I felt like a scuba diver having to come to the surface when she asked a question. We were sitting by the pond in front of the cabin when she asked how I could spend so much time alone. She said her friends admired my ability to isolate for a book’s sake but wondered whether it was healthy. I don’t think she was worried. She just found the ability foreign. I thought about it and told her something I’d learned about myself in the year I spent pursuing her. I’d learned my default mode was to perform. Even in small groups I feel like I have to be “on.” But when I’m alone my energy comes back. When I’m alone I don’t have to perform for anybody. She said I didn’t have to perform for her. She didn’t have to say that. I knew it was true. Who else do you marry but the person who pulls you off the stage?

Nicholas Carr (Is Google Making Us Stupid?)
Known as “Leni,” Helene Bertha Amalie Riefenstahl was born on August 22, 1902. During the Third Reich she was known throughout Germany as a close friend and confidant of the Adolf Hitler. Recognized as a strong swimmer and talented artist, she studied dancing as a child and performed across Europe until an injury ended her dancing career. During the 1920’s Riefenstahl was inspired to become an actress and starred in five motion pictures produced in Germany. By 1932 she directed her own film “Das Blaue Licht.” With the advent of the Hitler era she directed “Triumph des Willens” anf “Olympia” which became recognized as the most innovative and effective propaganda films ever made. Many people who knew of her relationship with Hitler insisted that they had an affair, although she persistently denied this. However, her relationship with Adolf Hitler tarnished her reputation and haunted her after the war. She was arrested and charged with being a Nazi sympathizer, but it was never proven that she was involved with any war crimes. Convinced that she had been infatuated and involved with the Führer, her reputation and career became totally destroyed. Her former friends shunned her and her brother, who was her last remaining relative, was killed in action on the “Eastern Front.” Seeing a bleak future “Leni” Riefenstahl left Germany, to live amongst the Nuba people in Africa. During this time Riefenstahl met and began a close friendship with Horst Kettner, who assisted her with her acknowledged brilliant photography. They became an item from the time she was 60 years old and he was 20. Together they wrote and produced photo books about the Nuba tribes and later filmed marine life. At that time she was one of the world's oldest scuba divers and underwater photographer. Leni Riefenstahl died of cancer on September 8, 2003 at her home in Pöcking, Germany and was laid to rest at the Munich Waldfriedhof.

A wave of relief washes over me at the sight of my brother, who looks as cool and competent as always, and Dante, who could have ripped that fucking scuba diver in half with his bare hands if he would have been in the pool with me.
Sophie Lark (Broken Vow (Brutal Birthright, #5))
Every day on Earth, our souls carry around a physical body whose cells are constantly growing, dying, and changing. Without these bodies, our souls couldn’t spend valuable time on the physical dimension learning and evolving. A scuba diver needs the warmth of a wet suit, a tank of oxygen, a compass, and a clock to wander the depths of the ocean. So, too, do our souls need the body to accomplish our tasks on Earth. And just as the diver’s oxygen tank eventually empties, our bodies ultimately stop functioning. The diver doesn’t spend his entire time underwater fretting about when his oxygen will run out. He knows that it will happen sooner or later, so he just enjoys marveling at the sights below the surface. He may be having a great time or just come upon an interesting shipwreck, but when the clock goes off, it’s time to go to the surface. There are no two ways about it. It certainly doesn’t mean that he can’t go back down again later. It’s just part of the experience. When the diver surfaces, he may slap on a new tank and dive back in, or he might lie on the boat and contemplate the journey he’s just completed. Throughout history, humans have looked upon death as something to fear. It’s fear of the unknown. It’s because God, in infinite wisdom, has awakened our awareness of reality while we’re in the depths of the ocean with a finite amount of oxygen, and we don’t know what will happen when the tank runs out. We don’t know that above the surface is the actual reality: our real “home.” We’ll dive with many friends, and when their tanks run out, they’ll have to go. We’ll miss them, of course, but when our time is up, we’ll see them topside. The last thing our friends would want is for us to spend the rest of our time mourning their absence. If we are to live with any measure of peace and die with any sense of acceptance, it is up to us to come to terms with how we view “death.
James Van Praagh (Adventures of the Soul: Journeys Through the Physical and Spiritual Dimensions)
None of us are born with even the most rudimentary knowledge of alphabets, words, or grammar. Though the human brain springs from the womb well prepared for speech, like an aspiring diver in scuba gear, face mask, and wet suit poised on the edge of a dock, unless the brain plunges headlong into the ocean of language it will never learn how to talk.

God, I really don’t want to hurt you.” “Are you trying to scare me again, Luke?” “Yeah, I’m trying to scare you. Warn you. Use your head, Shelby. You’re young, you’re sweet, and I’m just an irresponsible, horny bastard. You’d be making a mistake, getting mixed up with me.” She traced his ear with a finger. “Well, Luke, I’m already a little mixed up with you. And you got yourself mixed up with me.” “Shelby, I’m temporary at best. I’m not staying here.” “Me, neither. Is that it?” He sighed and shook his head. “I’ve been known to run through women like sharks run through scuba divers. I wouldn’t be good for you.” “Are you sleeping with a lot of women right now?” she asked him. He hadn’t been with a woman in so long, he had a hard time remembering the last one. That fact alone made him even more vulnerable to Shelby’s incredibly seductive charm. “There has been only one woman on my mind. My brain is like a frickin’ missile and if you don’t move out of the target, I’m afraid I’m going to end up doing some things you might hate me for later. And then your Uncle Walt is going to shoot me.” It only made her chuckle. “Do you always warn your women not to get involved with you before you swoop down and devour them?” “Never. That could keep me from getting laid. But I worry about you. You need to fall in love, I can smell it on you. And I don’t fall in love. I don’t put down roots and I don’t make commitments.” “You know something, Luke?” she asked, smiling. “I think maybe you’re more worried you might fall in love with me than the other way around.” “See, you shouldn’t think like that—” “I just said maybe. It’s not like I expect it.” “You don’t?” “I’m going to travel and go to school. You’re going to fix up your cabins and sell them. You’ve been very clear. You’ve warned me a hundred times. And now, I’m just warning you.” “You want a fling? With a guy like me?

Harlan Coben (Fool Me Once)
Find a quiet space where you can be alone and focus on the dive ahead. Slow your heartbeat, establish a deep breathing rhythm, close your eyes or gaze out on to the ocean. Get yourself into a nice peaceful zone. Put away any thoughts circling around your mind concerning other aspects of your life, particularly areas where there is something negative going on. You are going diving; there is nothing you can do about anything that is happening in your surface existence while you are underwater.

After 30 dives, I thought I knew everything. After 300, I was sure that I did. With over 3000 dives, I know that a surprise is always waiting for me. Also, I thought that I had great buoyancy after having more than 1000's dives. It was only when I took an overhead environment course, that I realised that there was a lot of room for improvement.

What matters is that you wish to improve & continue to have positive, safe interactions with the underwater world. Equally important is that you encourage others to do the same. This book will help you do both.

My Book event was kindly arranged by Brendon books of Bath Place, Taunton on 14th March 2024 I concluded my talk with a verse :- The tropical island of Sri-Lanka was surrounded by a flood Which swept a train right off its rails and buried it in mud We had always loved the place and made there many friends So I went on a kind of pilgrimage to help them make amends I took with me my Brother's french Wife and Arthur's Brother Fred I wanted to help not just myself but friends in need instead Asked Arthur C. who I should help, aware there'd be corruption There are always unscrupulous people in disasters and disruption He put us on to Valerie, Wife of Hector Arthur's SCUBA diver We thus found someone trustworthy instead of some conniver She introduced us to Stefan Birckmann a German fellow there Who was working hard to help children and others in despair In Hospitals and Orphanages, German Stefan staged events Of traditional Puppets he'd revived in villages of tents The puppets were a psychological boost were so short of resource So I donated a thousand dollars to keep them on their course The Unicef stepped-in to keep them entertaining I found helping so rewarding and then came home to find it raining So spare a thought for others when they're in their hour of need Stop thinking of only yourself and banish selfishness and greed.

A new survey of recreational scuba divers reported that 41 percent people face dental problems from scuba diving. From most of the people suffer with a pain from the increased pressure underwater, but some people experienced loosened crowns or cracked fillings. And an unhealthy tooth under water could face much more dental problems.

Most experienced scuba divers frequently use the Valsalva maneuver on descent to prevent “locking” of the tube. Scuba diving in the presence of preexisting dysfunction of the tube, when nasal congestion develops, or both are risk factors for severe tubal problems and barotrauma. It is probably not wise for individuals with chronic ET dysfunction to pursue the sport of scuba diving.

When Communist Party chiefs in Russia went fishing, scuba divers plunged underwater and put fish on the hooks. When they went hunting, specially bred elk, stag, and deer were made to saunter across the field in point-blank range. Everyone had a wonderful time. When the king of Afghanistan visited the Tajik resort of Tiger Gorge, he blew away the last Turan tiger in the country.

Article F: Alternobaric Vertigo and Eustachian Tube Dysfunction. Charles D. Bluestone, MD; J. Douglas Swarts, PhD; Joseph M. Furman, MD, PhD; Robert F. Yellon, MD. Case Report: Persistent Alternobaric Vertigo at Ground Level due to Chronic Toynbee phenomenon. Laryngoscope 2012;122(4):868–72. The term “alternobaric vertigo” was coined by Lundgren in 1965 to describe vertigo in deep-sea divers, but also referred to aircraft pilots in 1966. It occurs during ascent and rarely descent and is a result of asymmetrical middle-ear pressures. Classically the vertigo due to this pathogenesis is transient but may last for several minutes. It is frequently associated with nausea and vomiting. It has been reproduced in pressure chamber experiments with some divers and fliers, but has not been reported spontaneously at ground level (Figure F–1). FIGURE F–1. Alternobaric vertigo can occur during ascent in an airplane or when scuba diving. We encountered a 15-year-old female with bilateral tympanostomy tubes who manifested persistent severe vertigo, at ground level, secondary to a unilateral middle-ear pressure of +200 mm H2O elicited by an obstructed tympanostomy tube in the presence of chronic nasal obstruction. She had had long-term tubes placed due to recurrent and chronic otitis media. Physical examination revealed achondroplasia, which is an autosomal dominate disorder characterized by abnormal bone growth, short arms and legs, short stature and a large head, which is associated with otitis media. The pathogenesis of otitis media in these individuals may be related to abnormal anatomy causing Eustachian tube dysfunction. Balance testing was abnormal, Eustachian tube function tests revealed dysfunction of tube. Surgery was performed to replace the obstructed tube with a patent one, and an adenoidectomy and bilateral inferior turbinate reduction to relieve the chronic nasal obstruction. Postoperatively balance testing was normal, Eustachian tube function remained dysfunctional, but she had complete resolution of her vertigo following the surgery. FIGURE F–2. Pathogenesis of alternobaric vertigo due to the “Toynbee phenomenon” One tympanostomy was obstructed and when swallowing, she developed high positive pressure in the middle ear, but in the ear with a patent tube, the pressure did not remain in the middle ear. We believed this was a previously unreported scenario in which closed-nose swallowing insufflated air into her middle ears, resulting in sustained positive middle-ear pressure in the ear with the obstructed tube. Swallowing, when the nose is obstructed, can result in abnormal negative or positive pressures in the middle ear, which has been termed the “Toynbee phenomenon.” We concluded that in patients who have vertigo, consideration should be given to the possibility that nasal obstruction and the “Toynbee phenomenon” are involved (Figure F–2). CHAPTER 7 PATHOLOGY The pathology of the ET may or may not be involved in the pathogenesis of otitis media, whereas the
