What kind of exercises do you do to stay fit?
I jog, i can do over 100 press ups in a row and a us dumbbells 
You run your fastest in you 20s, but you can do better at long distances when your older!
Cool i did not know that , i remember when i completed my first jog around the block in Jacksonville, Florida thinking of quitting was in my mind but once i broke through that mental barrier i never quit at anything again
I can't imagine running in Florida. It's always very hot!
Yes could place to get a free tan 
I have never been to Jacksonville. I hear there is a lot of shoreline, so I would love to go to the beach there!
Yes plenty of shoreline and places to go and train to stay fit
I hear BlackFin Crossit is really good!
Your not wrong ! i have tried it a few times
