A man goes to visit his grandpa in the hospital.

"How are you,Grandpa?"he asks.

"Feeling fine,"says the old man.

"What*s the food like?"

"Terrific, wonderful menus."

"And the nursing?"

"Just couldn*t be better. These young nurses really take care of you."

"What about sleeping? Do you sleep OK?"

"No problem at all --- nine hours solid every night. At 10 o*clock they bring me a cup of hot chocolate and a Viagra tablet ... and that*s it. I go out like a light."

The grandson is puzzled and a little alarmed by this, so rushes off to question the Sister in charge.

"What are you people doing," he says, "I*m told you*re giving a 95-year-old Viagra on a daily basis. Surely, that can*t be true?"

"Oh, yes," replies the Sister. "Every night at 10 o*clock we give him a cup of chocolate and a Viagra tablet. It works wonderfully well. The chocolate m akes him sleep, and the Viagra stops him from rolling out of bed.
