Three men are sitting naked in the sauna. Suddenly there is a beeping sound. The firstman presses his forearm and the beeping stops.The others look at him curiosly.

"That's my pager," he says. "I have a microchip under the skin of my arm."

A few minutes later a phone rings. The second man lifts his palm to his ear. When he finishes he explains,

"That's my mobile phone. I have a microchip in my hand."

The third man, feeling decidedly low-tech, steps out of the sauna. In a few minutes he returns with a piece of toilet paper extending from his rear. The others raise their eyebrows.

"I'm getting a Fax," he explains.
