"Longevity"

A fellow who's just reached his 150th birthday was
giving a press conference to the assembled media.

"Excuse me, sir," one of the reporters said, "but how
did you come to live to 150?"

"It's actually quite simple," the old fellow replied.
"I just never argue."

"That's impossible," the reporter responded. "There
must be something else, like diet, or meditation, or
something. Just not arguing won't keep you alive
for 150 years!"

The old fellow stared hard at the reporter for several
seconds.

"Hmmm," he finally shrugged, "maybe you're right."
