Doctor: This is an old break.
Me: I've never broken my foot.
Doctor: Yes you have here... and here.
My feet are a mess, mostly because the shoes of the 70's were junk. So were the 80's and most of the 90's.
A good selection of decent running shoes has only been around for about 10 years. My running days would be over if I had to run in the shoes of the 70's.
