"Personally, if I do get a nuke or several dropped on or near me -
which is reasonably likely if I don't relocate off Oahu - and if I'm
not, y'know, vaporized - I'll use broken glass to sever an artery.
Once thing about suburban rubble, you'll be able to find shards of
broken glass, and it's the sharpest edge there is; it's what they use
to cut cells in half for electron microscopy. Broken plate glass has
a single-molecule edge, I think. And I can attest that bleeding to
death is not only painless, but even slightly euphoric - I lost 60+%
of my blood once to an arterial bleed."
