Every time I try to take my life I just get resurrected by some random amazonian tribe. It's kind of annoying to shake off a whole tribe of people thinking of me as their personal messiah, finding my way back to civilization through the worlds largest jungle, and building a new identity out of nothing because I'm officially passed on despite my numerous complaints to the state officials. Also, dying fucking hurts, so I'll pass this one.
But if I were to do it, I'd put great effort into making my flat waterproof and then simply leave the tap on.
