I’m not sure if this is qualified as a sign of getting old. This is something I never thought about when I was younger. I recently started to do this.
I like good burgers, but I don’t like it when my hand smells afterward. So, this is what I do.
I carry plastic sandwich bags in my wallet. They are so thin that they don’t take any extra space in my wallet.
When I eat a burger, I strategically place the sandwich bag in the napkins so my hand will not smell like onion.
See the plastic sandwich bag?
