My keys!
I always take my keys with me, even on a two week trip to Alaska when I had no real use for me keys. Just last week, I flew to Florida on a business trip. No real need for keys.
When I stand up, I pat my front pocket to be sure I have my keys, then my butt to be sure my wallet is there. Multiple times per day. As a geezer, I have never once lost my keys, or wondered where they are. Same with my wallet.
Last week in Florida we went to a local restaurant & bar. As we were standing in the bar area drinking a beer, waiting for our table, I noticed a guy's wallet had fallen on the floor. I walked over, picked it up and handed to him. His wife, grabbed it from my hand. Then he insisted he buy me a beer. It was the first and only time in my life a man I did not know bought me a beer.
