Interesting question. I smoke like a chimney (and I have asthma also), so strike one against me. On the flip-side, since I was robbed at gunpoint (short-barreled shotgun three feet from my chest held by one assailant, and a revolver in the hands of the other seriously-wired crackhead, and then kicked in the face after being told to lie face down, hostage style--resulting in three separate broken bones in the skull--nose, cheek and suborbital blowout of the eye socket), I've had agoraphobia so I don't leave the house much and hardly ever drive... So, I probably won't die in public or in a fiery car wreck. Although, staying home can be perilous... carbon monoxide or a gas leak (both unlikely), or maybe slipping in the shower and bleeding out... a lot more likely as I'm prone to being a klutz. Oh yea, armed home invasions seem to be gaining in popularity, so maybe I will violently buy the farm at home after all. Hmmm... You know, I may have occasional ideations of suicide when the depression and anxiety get out of hand, but I'm too much of a chicken-shit to actually kill myself, so that's probably not going to happen; and, I don't have any fetishistic desires to be killed violently (maybe just hung by the neck a little until I blow a huge load, but then I must insist on being let down before the fat lady starts yodeling a Wagnerian aria).
Upon reflection, I do recall dining out with my elderly mother one evening, and upon stepping out of the vehicle, looking up and seeing a rather intensely bright object in the sky. My first thought was of an impending asteroidal/cometary strike. My second thought was something to the effect of, "Wouldn't that be a relief." So maybe I do have a deeply buried desire to die.
However, all of the above food for thought, is in the end moot, as we're all going to die on December 21st when planet Nebiru collides with the Earth, time stops as a result of the Aztec calendar running out, the Earth aligns in conjunction with the galactic center exposing us all to a deadly gamma ray burst, the aliens finally invade, global nuclear warfare occurs started by the North Koreans and Iranians, a devastatingly deadly viral pandemic is released by a disgruntled scientist, and a black hole devours the planet from the inside-out, caused by those foolish physicists at the Very Large Hadron Collider, et cetera, et cetera, etc. Oh well, on the up side, at least I don't have to worry about the hassle of last minute Christmas shopping.
That's something to celebrate!
