I understand why some (especially here) might think manual labor is useless, but those more hardware-oriented people might understand the value. Even if you've worked on a lawn mower or jimmy rigged a gadget you might understand the potential gains. When you tinker with something you see why it works, how it might work better, etc. Sometimes a software architect needs to dig into the code. Sometimes a mechanical engineer just needs to work with the parts. This has the added benefit of putting the mind in a relaxed state where creativity tends to occur. I know there are studies along these lines, too, but I'm not great at tracking down or validating nuero/psych studies. I have no idea if the benefits I mentioned the intended result, but I think it's interesting. It may or may not be more beneficial to have people repair broken things, solve mechanical problems, or create non-standard parts from scratch to see what happens.
