Even opening a bottle cap requires the use of a tool.

When I was young, I wondered why people used various household tools. I thought I could do things easily by hand, so I wondered why bother using such tools. But as I got older, my joints started to feel different from before, and I found myself needing to visit the hospital. A few years ago, I went to the hospital quite often due to trigger finger syndrome, and I still haven't fully recovered. Since then, I decided to use tools as much as possible in daily life. The most simple and frequently used tool is a bottle cap opener. It is essential when opening water bottles, pasta sauce bottles, jam jars, etc., especially when a sudden burst of strength is needed to open the lid. Using this tool reduces the effort needed to grip with my hand, making my hand joints much more comfortable. I heard that the more you use it, the faster it wears out. Using appropriate tools can help delay degenerative joint disease even a little.
