Please, educate yourself a bit, environmental factors are meaningless against DNA expression...after maturity at least, sure, starving an underage teen will result in drastic changes, same as messing with hormones during those important metabolic changes, but you're not...right ?
Everything is related to your damn genome...everything, even your huge denial for Androgenetic Alopecia, you have it, nothing more to say, and you'll have it for life, and that's your parents doing, not your lifestyle, or some random events in your life, and you'll most likely pass it to your children aswell
