A lot of the pro bodybuilders, after they retire, admit that they have a very long list of medical conditions: shut down kidneys, enlarged hearts, no testosterone, etc. If you google it, most of the elites are dead before they turn 50.
I see Chuck Bednarik made it to 89 and passed just a day or so ago. He definitely was the nfl pre-steroid period. HGH is legal in Germany and I had read where Peyton Manning, Tiger Woods,and many others travel there a few times a year to partake. Not surprised..
