Do they have a mental illness? At some point, they should have figured out that they won't go pro, yet they still dedicate their lives to pumping their body full of drugs and eating 6-8 meals a day and living the "lifestyle"
What do you care at least they are following their dream, look at john meadows chase his pro card for 10 + years and finally got it so I guess he should have given up.
Well yeah I guess it is a kind of mental problem. Just like people who go to Hollywood and try be a famous actor and end up waiting tables for the rest of their lives.
If you cant make it to the top 5 as a pro, go do something else, the drugs required to stay competitive at that level without the earning power of being top 5 make it uneconomical to continue.
