people tend to think 'i'll walk into the mushroom cloud and instantly die' not linger for weeks/months severely injured, sick, and starving to death, but unless you live very close to a guaranteed target i wouldn't put money down on instantaneous not-having-to-bother. you'll actually have way more problems
I would much prefer to be launched into a black hole. On my right side, because I'm a side sleeper, plus then I can look out along the accretion disk and watch billions of years pass by before I get spaghettified and sucked into the mind of God.
