So…at least once a year? 
Ahem, I would now like to change my answer to being hunted down and taken out by Oakminster.
No worries. Unless you happen to be a windmill, in which case, shit be on, biotch. 
Meh. Back to heart attack then. 
Most likely in November of 2007 when CERN turns on their Large Hadron Collider ( link )
Accident or Illness (though I would really to my best not to think about it too much beyond that).
Probably either starvation, or some freaky disease contracted from a tree anteater. Or else cumulative chromosome damage and kidney failure from drinking two liters of generic pop every damn day for decades.
…Oh, Large Hadron Collider. Yeah, that sounds like a much more comfortable way to go.
I had a friend that said I’d die at the age of 26 in a skydiving accident. I’m 26, and also have a friend that skydives for a living and is always bugging me about going. :eek: If I make it another 20 years though I’d say I probably end up dead of a heart attack.
Suicide or a car accident.
Can you blame me if, after reading Oakminster’s lament about laidlessness, I read that as Large Hardon? (and you know those scientists have a blast with that).
20 years? Damn, I’d be only 51. Most likely car accident.
(Aside: Where ya been, Skaldy? Missed ya.)
Thank you.
Autoerotic asphyxiation
Well, since I live in NYC, and since our president is actively cultivating global jihad… yeah, don’t wanna think about it.
Car accident probably, I am on the road quite a bit…
I’m pretty healthy so I can’t imagine that I’d be dropping dead of a heart attack or anything.
Cancer, probably.
Either cancer or heart disease, both of which are fairly common in my family.
This is likely how I’ll go, sans oracle. I came a mite too close to this fate last summer - tripped on a crack in the sidewalk in front of my house, and fell headlong and fast. When I finally coordinated my movements enough to get my hands out in front of me, I was MILLIMETERS from having cracked my skull open on a cement ledge. I’ve been terrified of massive head injuries all my life, and I’m pretty sure it’s because somehow I KNOW that’s how I’m checking out.
I’ll probably die in traffic on my bicycle. Or heart disease.
In 20 I’ll be 63; I’m guessing that a motorcycle accident will take me before natural causes, if I don’t take care of it myself first.
Complications from obesity: heart disease, diabetes, or something similar.
And twenty years seems a long time, at the moment.
