Okay, I'll get things started by posting the tip on Facebook on how to open a jar!
"If you have some strong rubber bands, placing one around a jar lid gives you a better grip to try to open a jar. If you are unable to place it on there, get someone else to do it. Rubber band on lid, covered with a dish towel helps. For new jars, run some hot water. In a pan, hold jar upside down with lid under water, often breaks the seal for you.
I drink bottled water and have a bottle top opener that I use to open bottles, or ask son or grandson to open for me. Eating peanut butter is soothing to your joints, so they open those jars for me. I try to keep a jar beside my bed to eat some on achy days."
