It may be rare, but even in our modern civilized society people most certainly need to “run for their life” on occasion. I’m sure it happens somewhere in the US everyday. On 9/11 there were thousands forced to do so. It is no stretch to say that those who spent time conditioning themselves for running were better able to escape harm, or rescue others, than those who never did because they thought running was boring or hurts too much.

But the need to run need not have as noble a reason as saving a life. It could come in handy when chasing down someone who just grabbed your bike, or when trying to be the first person to get the $99 Plasma TV at 5am on black Friday. There also was the time I almost missed the ice cream truck and had to chase it down for 5 blocks on foot…

My point is that if you never run, eventually you'll never be able to.
