If you spent 30 years doing something, that's means you haven't been doing something else.
Bodybuilders and personal trainers . . . fitness is all they got.
How do you expect them to make money later on in life? It has to be something fitness related. Or, you start at the very bottom at something else like a 21 year old and not use your 30 years of fitness at all?
That's the corner all fitness people have painted themselves into.
