Three men - an American, a Japanese and Banta Singh were sitting in the sauna. Suddenly there was a beeping sound. The American pressed his forearm and the beep stopped. The others looked at him questioningly. "That was my pager," he said. "I have a microchip under the skin of my arm." A few minutes later a phone rang. The Japanese lifted his palm to his ear. When he finished he explained, "That was my mobile phone. I have a microchip in my hand." Banta felt decidedly low-tech but not to be outdone, decided he had to do something just as impressive. He stepped out of the sauna and went to toilet. He returns with a piece of 'Toilet paper' hanging from his butt. The others raised their eyebrows and said, "Wow! What's that?" "I'm getting a fax," he explains
