Suddenly, a beeping sound went off. The first young woman pressed her forearm, and the beeping stopped.

The others looked at her curiously.

"That was my pager," she explained. "I have a microchip implanted under the skin of my arm."

A few minutes later, a phone rang. The second young woman raised her palm to her ear. When she finished her call, she explained, "That was my mobile phone. I have a microchip implanted in my hand."

The older woman felt rather low-tech. Not to be outdone, she decided she had to do something equally impressive.

She stepped out of the sauna and went to the bathroom.

When she returned, there was a piece of toilet paper hanging from her rear end.

The other two women raised their eyebrows and stared at her in amazement.

"Well, what are you looking at?" the older woman finally said. "Look at that... I'm getting a fax!"
