Well - I believe there are MANY contributing factors that lead to heart disease and IMHO it's not "all" genetic. At the rate people are getting heart diseas, if it was genetic, none of our ancestors would have made it
I've been reading about too many other lifestyle factors that can cause heart (blood vessel-type) problems for it to be coincidental. While "abuse" of 'roids "may" be a contributiong factor, I think there's a LOT more with scientific backing that as a general public, most are just ignoring.
I recently made a post about dioxins.
I just read another article on Clorine that SCARED the HELL outta me. I thought that by letting my water sit for at least two days, all the chlorine dissipates. But, depending on the number of particulates in the water (more is worse) the end result is trihalomethanes, which is a cancer-causing agent. I'll post the link if you guys want. I drink at least 4 qts of water a day, and it's probably been contributing to my early demise
