saw this on another web site,hits the nail on the head
It is much like someone who has walked 20 miles up a steep hill after 2 days of no sleep,carrying a backpack full of rocks on the hottest day.It is that moment that your legs can no longer carry you and every muscle and bone hurts.As soon as you sit down or fall down you are asleep for 5 minutes and a tornado could come by and not wake you.This Sums it up pretty good, it's great we are more alike than we think
