[Cthulhu_]

I'll admit the act itself can be a not very stimulating exercise (ha), but there's a few counterpoints. One, doing the work, breaking your previous achievement gives a lot of satisfaction. Second, you'll look better. Third, when you need it you'll have it - for example when you're moving house or helping someone do it, DIY work, etc. Of course, if you're affluent enough you can pay others to do it so you'll never realize when physical (and grip) strength benefit.
