Three in a Sauna

Three women, two younger and one senior citizen, were sitting naked in a sauna. Suddenly there was a beeping sound. The young woman pressed her forearm and the beep stopped.The others looked at her questioningly. "That was my pager," she said. "I have a microchip under the skin of my arm."A few minutes later, a phone rang. The second young woman lifted her palm to her ear. When she finished, she explained, "that was my mobile phone. I have a microchip in my hand."The older woman felt very low tech; not to be outdone, she decided she had to do something just as impressive. She stepped out of the sauna and went to the bathroom. She returned with a piece of toilet paper hanging from her rear end. The others raised their eyebrows and stared at her.
The woman finally said, "well, will you look at that...I'm getting a fax!!
