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