A great solution for emergency medical help

When it comes to finding interesting stuff at random, there really is no place better than the Internet. I came across a site that sells medical id tags as jewelry, so they can be worn at all times and have the information on them, in case of emergency. It's a good idea since a lot of people don't bother carrying this information with them, and end up getting into trouble if they are in a new place and have a medical problem. At first, I thought it just to be a marketing gimmick, but the more I think about it, the more it seems to make sense. A lot of people carry such information on a card in their wallet, but wearing it as a pendant or on a bracelet is a better way, I think.
