Received a leather wallet for Xmas 45 years ago when I got my driver’s license. Stuck it in my back pocket for a few weeks, only to realize I kept getting some serious sciatica in both legs. So, experimenting, I moved the wallet to the front pocket and the pain went away. Thought it was just me until college when others told the same story with some variations.
The leather wallet gave out 15 years later, and lacking time to buy a new one, substituted a nylon neck pouch. That was 35 years ago. It’s only now that I’ve noticed the beginnings of wear and tear. And thanks to this thread, I gave it a little needle and thread and hope it lasts another 35 years.
