What is strong?

Is it a muscle or is it somthing else. Is it measured in miles or mili seconds? Is it your best time? or your worst day?.
May be strong is what you have left when you have used up all your weak.

(Runners mantra)

Strong is not the one who never falls, but the one who allways stands up. (Ghandi)

No matter what you do in your life, it will be irrelevant, but it is very important that you do it. (Ghandi)

When keeping on gets tought the tought ones keep on. (From the T-Shirt of a 62 years old marathon runner)

What people says, doesnt say much about who they are. What they do, defines them. (me)
