If an archaeologist of a future species finds me in the rock I say dig me up, scrape my bones for DNA, measure my cranium capacity, and put my ring on display in a museum. This is as close to immortality as a person can achieve.
Might I suggest the cremation diamond route. You are cremated, the ashes are compressed to form a diamond... Choose your color. My preference is to be set into a belly dancers jewelry. Then women will wear you in their belly buttons for the ages.
