People in this thread are delusional. You think he started doping at 40? LOL...like start living in reality.
Professional athletes all dope or use something like a TUE to skirt around doping controls. Whoever your favorite runner is right now, they are doping.
This stupid stuff about 'nice guy' has nothing to do with it.
What people need to realize is that it has nothing to do with being nice, bad, wrong, etc. If you are a pro you have to dope because other pros dope. It's evening the playing field.
If you are in an Olympic final, play in the NFL, NBA or MLB - you basically have to dope. Period. End of discussion.
