Would you rob a bank for enough money to make sure you never worked another day in your life?

I told myself for years when I got old and feeble, as I now am, i would rob a bank. If I got away with it, fine, if not then prison would be better than dying homeless in an alley on a cold bitter winter day. I did some research on bank robbery for a novel I wrote and about the only way to get away with it is to use a computer. And banks don't keep enough cash at the counter to be worth the risk.
