Interesting fact: here in N.Y. if you are over 70 you have a choice to serve or not serve, although you must appear in person to make that choice.
Also, the bells went off when I was going in. They never found out what it was that set the bells off and passed me through anyway. Someone told me that if you have recently had that heart test, where you drink the radioactive material, that will set off the bells. (?????)
