True story: I had a blood test at Mayo this morning and was sitting next to three older folks who were talking to each other.

One lady talked about her artificial knee. Another said she had ten screws in her ankle. Then a man mentioned the metal plate in his back. After some silence, they all kind of glanced over at me and I said "well, I've got a couple of fillings in my teeth". They all laughed and told me how much I had to look forward to in my 'golden years'.
