After We Die - NYTimes.com James Atlas implies in "Choosing Our Final Resting Places" (Sunday Review, Feb. 19) that there are but two options for our bodies when we die: "ashes" or "dirt" - cremation or burial. But there is a third possibility: donating one's body to a medical school. Three immediate advantages come to mind: organs may be given to people in need; future or practicing doctors may become better physicians because of their study of the bodies; and it costs nothing. After the studies are completed - normally in two to four years - the body is then either cremated and returned to the next of kin, or cremated and buried with a ceremony in a plot of ground set aside by the medical school. Family members may attend.
