My old hands are quite stiff, so I found the same solution as you, John. I kept an old, non-childproof bleach container cap, and when I buy a new one, just transfer the caps. They all seem to be the same size fortunately. I can't possibly press the things down while turning them, my finger joints would scream! I also jab a hole in the tops of jam and honey jars, removing the vacuum. They open easily after that. (But of course, they're no longer airtight!)
