Neuroscientist Moran Cerf of Northwestern University has found scientific evidence to prove that long-term happiness depends on who you’re friends with. He says that when two people are together, their brain waves will sync, becoming nearly identical. “The more we study engagement, we see time and again that just being next to certain people aligns your brain with them. This means the people you hang out with actually have an impact on your engagement with reality, beyond what you can explain. And one of the effects is you become alike.
