With Memorial Day coming up, and law enforcement putting on another seat belt blitz, it's good to know that we're pretty good about wearing our seat belts in the Lone Star State. I don't think I ever see anybody driving without their seat belt on, at least not in a long, long time. It seems like the law if firmly engraved in our brains, and it's totally natural to buckle up before you go anywhere.
A blood test that should be available in Europe by the end of the year could give you a pretty good indication of how fast you are aging and how much longer you will live.
The test measures telomeres, structures on the end of each of your chromosomes, which scientists think may hold the key to determining a person's "true age."
