One interesting thing to research is the Social Security Death Index. This is a listing of people whose death has been reported to Social Security since 1962. This searchable index allows you to check on people from your past to see if they are still around. You can also do some research on your family. It is impossible to resist putting in your own name. See how many people you share a name with have already gone to the Great Beyond. It is a little unnerving to see your name and a date of death next to it. Might get you to make better use of your time.
