A middle aged man goes to the doctor and says, "Doctor, I would like to live very long. What should I do?"

"I think that is a wise decision," the doctor replies.

"Let's see, do you smoke?"

"Oh.. Half a pack a day."

"Well, starting RIGHT NOW, there's no more smoking."
The man agrees.

The doctor then asks, "Do you drink?"

"Oh, well Doc, not much, just a bit of wine with my meals, and a beer or two every once in a while."

"Starting now, you drink only water. No exceptions."
The man is a bit upset, but also agrees.

Then the doctor asks, "How do you eat?"

"Oh, geee, you know, Doc - normal stuff like meat, fish, cheese, eggs, rice and potatoes."

"Starting now you are going on a very strict diet:
You are going to eat only raw vegetables, with no dressing, and fruits."

The man is now really worried and says:
"Doc, is all this really necessary?"

"Do you want to live long?"

"Well, yes, but . . . ."

"No buts about it then! It's absolutely necessary.
And don't even think of breaking that diet". Now the man is quite restless, but the doctor continues...

"Do you ever have sex?"

"Yeah, once a week or so.... but only with my wife!" he adds hurriedly.

"As soon as you get out of here you are going to buy twin beds. No more sex for you! Absolutely none."

The man says.

"Doc..... Then what's the point in living longer this way??..."
