A Munchkin is the sort of person who, faced with a role-playing game, reads through the rulebooks over and over until he finds a way to combine three innocuous-seeming magical items into a cycle of infinite wish spells. Or who, in real life, composes a surprisingly effective diet out of drinking a quarter-cup of extra-light olive oil at least one hour before and after tasting anything else. Or combines liquid nitrogen and antifreeze and life-insurance policies into a ridiculously cheap method of defeating the invincible specter of unavoidable Death. Or figures out how to build the real-life version of the cycle of infinite wish spells.
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.
Yes, stop all meals. You can get something a bit like a meal if you do a very high-value highly-rewarded task. Also, I let myself eat whatever I want for a few hours after doing something sufficiently awesome (such as accumulating sufficiently many CoZE points, or when I spent 3 hours coding up a system to implement another lifehack thing).
My eating habits are a lot less healthy than they used to be - chips, fruit juice, candy, chocolate-chip cookies, etc., but also healthier things like nuts, popcorn, sandwiches and meat. If you do a high-value, highly-rewarded task, you can finish things quite quickly. At the moment I feel like health isn't as important as good reinforcement, but I'm planning to research that more.
I don't do much social interaction (I don't value it highly terminally, and most of it is instrumentally useless) but have broken the system twice to eat lunch with people, and put it on hold for 3 days while away at a college's admit weekend.
