I did not know that yesterday!

It's the darnedest thing. We were all doing just fine before cell phones came along. But now that they're here, nobody can live without them. So who do we have to thank/blame for the indispensable lump of plastic that costs us $50 a month? A chap named Martin Cooper.

Cooper developed the cell phone in 1973 while working for Motorola. Naturally, he had the honor of making the world's first cell phone call. From a busy New York sidewalk, Cooper called his rival at Bell Laboratories and said, "Joe, I'm calling you from a real portable cellular telephone." Cooper says he thought he heard teeth gnashing in the background.

Of course, the first cell phone looked a lot different than the fancy flip phones of today. And cell phones didn't go into commercial service until 10 years later, when Motorola introduced the $3,500 DynaTAC phone. Not surprisingly, at that price point, it took a while for the invention to catch on.

Today, more people subscribe to cell phones than landlines. For better or for worse, Martin Cooper's invention is here to stay.

Your skin is comprised of two layers -- the epidermis and the dermis. The epidermis produces an oily protein called sebum, which is effective in repelling water. It's also the material that causes fingerprints.

Inevitably, a nice long soak in a bathtub sloughs off the excess sebum from your epidermis. As a result, your skin starts to take on water. The top layer of the epidermis is known as the stratum corneum, which is Latin for "horny layer." These are the tough, dead skin cells that are constantly being sloughed off your body in your clothes, your bed, and in the form of dandruff. Disturbing, but true.

Your fingers and toes have especially thick layers of stratum corneum. Once deprived of sebum, they swell up with water, causing wrinkles. This osmosis effect is harmless and temporary. One you get out of the tub, the extra water evaporates, leaving your skin even drier than before because there is no sebum to help retain moisture. This is a good time to apply lotion or oil to help your skin retain some of the water.
