What is "personality"? How much of that is choice? And for the neuroplasticity and are the dopaminergic system differences, how much is cause and how much is effect? Our actions affect our brains and the rest of our bodies, and vice versa. If I chose to lift heavy weights every day, after ten years you wouldn't say, 'they do that because they have extra muscle'. |
