Take care of your body! They are liars! Brain doesn't get you through 20 miles of jungle, brain just SITS there. You need to move? WELL THEN YOU NEED TO MOVE! And if you can't? SUCKS TO BE YOU! Don't buy that line that you can talk your way or think your way out of anything, be ready to run, be ready to crawl, be ready to jump, or you'll die before you get to kiss your sweetheart.
