Well, I think you are approaching it the best way. Do it while you can becuase once you get in your middle to late  40s you might see a sharp decline in physical prowess.

Not saying for sure. Everyone is different . But trust me ,it won't last forever  :)

If you're like me you just end up switching Passions and not get all sentimental and down and out because  you can't do the things you did when you were 20. Just part of Life
