I worked in a bank and I read the obits every day, hoping to see my
boss's name there.

If you have important info on your computer, backing it up onto CD or
DVD and storing the disks off-site in a safety deposit box is a good
idea in case of fire, flood, tornado, burglary, etc. Or you could just
leave the disks at your office, in your gym locker, at a friend's
house...

If the banks do read the obits, how do they know it's their customer?
Don't people named John Smith die every day?
