Wow. Just...wow. You know, that same anthology of Iron-age pornography says you can get two white goats to have spotted kids by making them stare at a stripey stick while you breed them. I have to wonder what your criteria are for what you do and don't accept on its face...
As to lifestyle...no, buddy. Smokers choose to smoke. (Most) fat people got that way because they choose to overeat and/or not practice good nutrition. I did not choose to be a lesbian. It'd be easier overall if I weren't one, but it wasn't a choice.
If you don't believe me, here's a thought experiment: try to make yourself gay. Right here, right now. Try and will yourself to like men and only men, and have no native attraction to women any longer. I don't mean suppress your feelings for them; I mean by pure force of willpower eradicate them entirely, such that not even your autonomic nervous system reacts to a pretty woman anymore, but does attract you to other men.
