I'm finding that my left thumb has been getting tired the more typing practice I do, and so I've started switching over to my right thumb here and there. But I wonder whether it's worth learning to switch thumbs depending on the key, the same way you switch Shift keys depending on which hand it's easier for. What do you folks do?

Edit: This was interesting to read; thanks everyone. It seems like there are definitely some people out there who are used to switching between thumbs depending on which finger they used last; as u/BigGuyForYou_ mentioned it sounds difficult to get into but I think I'm going to try it out!
