This just in: Pro athletes are fast

I may have said this before, but this blog's been here for 6 years now so if I'm repeating myself, please bear with me...

If you would like to know how fast Olympic sprinters or NFL players are, try running a 100-meter or 40-yard dash, and compare your times to theirs.  This works even better if you fancy yourself pretty speedy in your own right.  You'll see just how wide the gap really is. 

And when considering how slow the biggest NFL offensive and defensive linemen are, just remember that they only look that slow compared to the rest of the blazingly fast players on the field.
