I can sort of appreciate the benefits of this, but their methods make no sense to me. The way I figure, I can get the same benefit from choosing to commit to "not-do" pretty much anything for a month, so it shouldn't suck any more than it needs to. Furthermore, the benefits of committing to not-doing not-something follow as easy corollaries.
During this thought process, I remembered that God gives you extra points during this month for not-doing things. I've decided abstain from not cooking something on a grill at least once a day (per sleep cycle, really), and to give Haiti all of the points I earn by doing so. In other words: I plan to cook something on a grill at least once a day. For forty days. For Haiti.
I cannot conceive of any way that this plan could go wrong.
