My mother donated her body to a teaching hospital, where they used the cadaver in classes. A year later, they burn them anyway so we got a box of ashes back, which are buried next to my Dad's in the CT town where I (mostly) grew up. I've visited their graves a few times--but I live too far away to get there much any more. I've arranged to donate my body to a teaching hospital, too -- although here in Colorado my estate will have to pay the cost of transportation. (Cheeky ingrates!)

If you're planning to live forever--so far, so good.
