What if they just decide they no longer want to live the lifestyle? Why is that bad?
I guess I have to put my viewpoint in perspective. I have been around this game for a long time. One of the most common things I hear from hard core steroid users who don't train anymore is that they say a variation of this, "training without steroids is a waste of time."
For me and many others working out is real physical culture and a life style. Leaving training to me shows you never had any true dedication. Iron is something the is ingrained in a work ethic that shows the character of your soul. It could come from an example of a hard working father. The work ethic can come for a tough life. How ever it comes from the end point is the same. There is virtue in the struggle. It's bad because it shows a lack of honor as a warrior. These guys love to pull a crumbled picture of them self out of a wallet to show how they looked back in the day on cycle but funny they never mention the drug use. One guy who quit training pulled a picture out of his wallet and I told him I don't need to see that you're standing right in front of me.
I admire guys like Bill Pearl, Robby Robinson and Dave Draper. They will train until they can't do it anymore. Guys like Kalman Szkalak rarely lifts anymore but he got into elite road bike age bracket racing. He's one of the top dogs in bike racing. Another top amateur competitor Joe Means does bike races and sprint triathlons. I respect that.
One last point. There was a guy on my job that use to run on occasion but never anything serious. Maybe a charity 5K. He retired and moved to the South for the good weather. Then tragedy hit and his wife died. He didn't know anybody in Florida being from NJ. He saw a thing on the internet for a local running club. Due to his age and that he gave up any modest running that he did he had a tough time. Long story short he's in his 70's and can run 26- 7 minute miles. That's about 8.5 MPH on a treadmill. Most guys in their 20's and 30's couldn't do one mile at that speed. That's passion. That's what I respect.
