Does anyone know if there's science to back this up? The brain is a malleable organ. Every time you do an activity, or have a thought, you are changing a piece of yourself into something slightly different than it was before. Every hour you spend with others, you become more like the people around you. Gradually, you become a different person... You will become more hedge fund, less malaria. I've read studies that show the more you expose yourself to a song or a person, the more you'll like it/him, even if you started off hating it/him. But that doesn't mean you become more like the person.
