I once asked my grandfather how he'd lived so long He smiled and said; "I sprinkle a little gunpowder on my cereal every morning."
I always thought that was a little weird but he did live a long life and left a great legacy; a thriving career, loving wife, seven children, sixteen grandchildren, two great-grandchildren, and a massive hole in the crematorium wall.
Once there was a doctor who got shot. He adamantly wanted to perform surgery on himself, despite all of the other surgeons saying that he shouldn't. But he was so insistent that they finally said "Fine, suture self."
I dated a doctor once. Big mistake. She was a Psycho.
