All fair points, to which there might be workarounds... but the title of the post is "Post Ridiculous Munchkin Ideas".
Seth Robert's idea of putting a noseclip on your nose while you it to lose weight is ridiculous to most people. It's not ridiculous because there are practical problems with putting noseclips on your nose.
It ridiculous because normal people just don't put noseclips on their noses when they eat. If there are practical problems with implementing your idea why should a munchkin do them?
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
