A man goes to a hospital and sees a man masturbating.
He asks the nurse why is he doing so.
The nurse explains to him that if he doesn’t masturbate every 6 hours there would be a clot and he would die.
Then in the next room, he sees a nurse giving a blowjob to a guy.
He then says, “You will have to explain this.”
The nurse replies, “Same problem better insurance.”
