You dont have a clue if you think there is a difference in drug addicts. I wonder if Rush and the sainted Mr Favre got all their drugs legally? Weak people who cant control themselves.
Rush, no. Brett Favre, yes and no.
Farve, had prescriptions, then again Farve deals with more physical pain then most folks, but Farve also, at the same time, was also getting the same pain killers from his teammates.
I'm not sure whats weaker, quitting and retiring from pain and hurt, or taking vikes so you can live in pain and hurt for more years.
Farve's self control is pretty well known, as he has never missed a game, and has a consecutive streak going.
If Farve is weak then a big rig is a skateboard.
We all have our weaknesses. Some people fall victim to addiction. Other people can't detect moments when they should just shut up.
