“Sixty is the worst age to be," said the 60-year-old man. "You always feel like you have to pee and most of the time you stand there and nothing comes out."

"Nah, that's nothing," said the 70-year-old. "When you're seventy, you don't have a bowel movement any more. You take laxatives, eat bran, sit on the toilet all day and nothin' moves!"

"Actually," said the 80-year old, "Eighty is the worst age of all."

"Do you have trouble peeing, too?" asked the 60-year old.

"No, I pee every morning at 6:00. I go like a racehorse peeing on a flat rock; no problem at all."

"So, do you have a problem with your bowel movement?"

"No, I have one every morning at 6:30."

Exasperated, the 60-year-old said, "You pee every morning at 6:00 and crap every morning at 6:30. So what's so bad about being 80?"

"I don't wake up until 7:00.”

I strongly reccommend not getting old.  As I read this, I did not find it funny, I just accepted it as statement of fact of a fellow oldfart's normal day.
 It's kinda like drinking coffee.  After a few years it actually tastes good enough that you will even drink several cups in a row without spitting it out.  I wonder if people in India who drink their own urine....  Nevermind.
