If captured we couldn't spill the beans because we'd forget where we put them. In fact, name, rank, and serial number would be a real brainteaser. 
 
  Boot camp would be easier for old guys. We're used to getting screamed and yelled at and we're used to soft food. We've also developed an appreciation for guns. We've been using them for years as an excuse to get out of the house, away from the screaming and yelling. They could lighten up on the obstacle course however... I've been in combat and never saw a single 20-foot wall with rope hanging over the side, nor did I ever do any pushups after completing basic training.  Actually, the running part is kind of a waste of energy, too. I've never seen anyone outrun a bullet.
 
An 18-year-old has the whole world ahead of him. He's still learning to shave, to start a conversation with a pretty girl.
He still hasn't figured out that a baseball cap has a brim to shade his eyes, not the back of his head. These are all great reasons to keep our kids at home to learn a little more about life before sending them off into harm's way.
 
Let us old guys track down those dirty, rotten, coward terrorists. The last thing an enemy would want to see is a couple million pissed off old farts with attitudes and automatic weapons who know that their best years are already behind them.
 
HEY!! How about recruiting Women over 50...in menopause!!!  You think MEN have attitudes??Ohhhhhhhhhhhh  my God!!! If nothing else, put them on border patrol. They'll have it secured the first night!
 
If you send this to your senior friends make sure it's in big type so they can read it.
