How do you think you will die?

Helium mask.
I went through a serious bout of cancer when I was 30 and saw what it looks like trying to fight the inevitable. I've been cancer free for about 9 years now, but the suffering I went through and saw in others left its mark on me.
When I do finally get sick again, I will go out on my terms, not the disease's.
- Don't use the helium gas for balloons, its mixed with enough oxygen to keep you alive, use nitrogen or argon from welding supply places.
- I have a book about this, and I think it's good to plan ahead.
  I'm also too scared to read the book because I struggle with suicidal thoughts, and I fear I might make the decision too soon, when I'm in fairly good health.

I'll probably get bodied by a massive SUV while cycling
- I wrote basically the same thing before seeing your comment. Stay safe, hope you keep the rubber side down.
  (I'd hope for safe bike infrastructure but I don't believe in Santa anymore.)
- Lol probably same for me. Already got bodied (lightly) once, half of my back was all tones of yellow, brown and purple for a month. Thankfully only the soft tissue suffered. Always wear a helmet! The bastard took one hell of a beating that day but at least my head was completely fine.

My username

By nobody stopping me from building my own helicopter.
- You joke, but my dad literally built (most) of his own helicopter. My mom wouldn't let him fly it because of us kids haha. He sold it still incomplete

One side of my family is all heart disease, the other side is all cancer.
I'll obviously find a way to die of heart cancer.
- Jesus that would be like a 1 out of 10,000,000 thing to develop
  
  well there are 8 billion people so

My main mode of transportation is a bicycle and I live in North America. I will likely die spread out on the asphalt when someone runs me over with their oversized SUV/truck after they blow through an intersection out of turn while on a Facetime call.
No amount of defensive riding will protect you against that, unfortunately.
- This is the main reason I don't cycle.
  
  You’re definitely not alone

Probably suicide.
- I read the tile as who do you think will, and was confused seeing this

  You ok mate, iam open to talking if you want. DM me or if you have a matrix account , iam at @barafur:matrix.org
  
  As someone who has always felt the same way, look. Time eventually runs out, and age and disease catches up to us. Hard labor wears us the fuck out. Some pain never stops. There's only a few things that keep me going; I'm convinced that humanity needs people with my perspective on climate change and fascism. Both must be fought til death. There are also people I love who I don't want to hurt. Finally, maybe we'll find an alien civilization soon! And so I go on.
  But there are limits to what I will fight. I've watched a friend die from brain cancer. I will not go that way. I'll choose my own path.
  
  Very kind. Almost certainly not going to happen for a few years until only non-dementia parent dies.

I hope it's not for a long time. I grew up seeing my great grandmother age gracefully and finally pass in peace in her favorite chair reading John Grisham novels. I admired that woman so much, despite the fact that she lived alone, her life partner long gone, she enjoyed her humble life in her cozy home.
I hope to do the same, for my heart to just stop beating in my advanced age. I've told my family that I don't think I'll mind even if I'm the last to go, I want to see how it all ends. I want to see the good and the bad of everything. I want to live as long as I possibly can.

I've thought about this, and having worked in hospitals and nursing homes, I've seen a lot of people die, so it's given me some perspective.
My husband is the closest person to me by far. He also has a lot of chronic health problems. I suspect he will pass away before me.
The older I get, the fewer people I have in my life. In my 20s and into my 30s, I had a lot of friends, but little by little they've fallen off. I've got a couple friends in my MTG playgroup and one friend who I go longboarding with in the summer, but beyond that, I've pretty much lost touch with everyone. This only gets worse as time passes.
Best-case scenario is that I die in a nursing home or hospital, completely alone. Maybe my nieces and nephews might visit sometimes, but there's no way I'd ever see them frequently, nor should they feel compelled. I'll be old and confused in a strange scary place, with people talking in that condescending baby voice that I saw a lot of CNAs and nurses use. If I'm still able, I can play video games or something up until the end, but I have reason to suspect I have the beginning of Parkinson's like my dad, so slim chance of that. I'll just die staring at the ceiling, in a completely emotionless void.
Worst-case scenario (most likely) is that I get put in a nursing home but evicted for being too poor. Then I'd just die faster out on the streets or something, or in a shelter. And come to think of it, this might actually be the preferred scenario.
Either way, I'll certainly die alone and unloved.

Cancer is a fairly safe bet; I'm in the western world.

My luck I’ll somehow live forever; if only to suffer the consequences of life. But if I had my way, I’d love to go “peacefully” in my sleep. Just lay down one night and never wake up.

I've planned my death, but I won't tell anyone the details because I don't want to be distracted from the experience.
I'm not depressed or suicidal. It's something I've planned for old age, when I'm becoming invalid.

Statistically? Cancer or heart disease.

I will live forever. Or die trying!
Biotech revolution is coming!

My great-great-grandfather was murdered by an iceberg in 1875 and some days I feel a mysterious chill breeze that suggests it's still out there and not finished with my family. Or my arse. Probably that now I think of it.
- I think your great grandfather made a deal for a stupid large amount of money, but instead of a snail it was an iceberg that would kill him
  
  The family would like to know where the magic iceberg money went, as we never saw a penny of it.

I have an infallible Machine of Death Certificate indicating I will die of "knife justice".
- Ok that sent me down a rabbithole I didn't know existed. Thank you?

Heart attack or stroke
- Yeah. Probably with a bunch of ignored symptoms leading up to it.

Self-inflicted.

I don't think I will.
- fate be a cruel mistress. won't let me go, gonna make me suffer for decades more.
- Yeah, I was thinking about not bothering with it either.

Ah the twin question to how do you want to die. I don't know but live in a city with many traffic deaths, am old enough to die from heart attack, my grandma (the one I take after the most, physically ) got Alzheimer's, my mom got a bladder infection when old, got hospitalized, didn't recover.
I take good care of myself so guessing, sadly, dementia when old, as it's not really totally preventable yet and I'm not prone to cancer. Maybe stroke since I'm a migraineuse but we live very close to hospital and know the signs.

This has changed over the last 15 years.
For the longest time I was sure it going to be by my own hand. I had looked at different methods of suicide. I had very bad depression and I thought about it a lot. I eventually started treatment and while it was still a struggle and in no way cured my depression, it helped me make changes in my life that took me out of the situations that exacerbated the depression. I also started treatment for my ADHD.
Now, I'm not so sure. I still have the occasional bout of hopelessness, crying, and ideation. But it's rare now. My girlfriend and her daughter are moving in soon and I'm starting to be optimistic about the future.
Now it's probably my health, a car accident, or I blow myself up somehow.
I don't exercise and I work from home. So I'm overweight and don't move as much as I should.
I like to drive and let's be honest, it's a dangerous method of travel.
I work with explosives. We make it as safe as it can be and it's unlikely something will happen, but it's an inherent risk of the profession.
- Congrats and good luck not exploding

clipping out of world and ragdolling into a mole at terminal velocity

Cardiac arrest as a result of blood loss secondary to hereditary hemorrhagic telangiectasia.
Which is why, when something bad happens, I get to say the exceedingly cool, "I know what's going to kill me, and this isn't it."

Family history of cancer. My grandmas from both sides had it. Other family members died from it. So, probably from some form of cancer or sickness.
If not, probably due to a motor vehicle accident (motorcycle, ATV, Snowmobile, car) or some other form of stupidity.

To all the people who are saying suicide dm me we can start a death cult (jk really though if you want someone to talk to i'll always be there for you just dm ).

With a bang.

Heart disease or cancer

Homeless, dead of exposure, under a freeway overpass.

As a conscript in the Water Wars of 2032.

Entropy

Cancer or climate change, or my escaping the effects of one/both.

Exposure to the elements.
- All of them, at the same time.

In a motor vehicle accident.

i'd like the James Gandolfini. die on vacation somewhere nice.
how'd he spend his last week? worried about the bills and work? no, on vacation in Rome.
we should all be so lucky.
also, i kind of hope my death causes a lot of paperwork.

Old
Suicide
By traffic accident

Starvation after all the people supporting me die and I refuse to get help any other way, eventually leading me to forget to go shopping for food until I'm too hungry to get up, leading me to just wait for death to take me.

Deterioration of the mind. At two decades old, I have all the ingredients for that eventual setup. Either that, or my lack of good experiences gets the better of me.

Heart attack. I’ve had a lot of problems with strep in my life due to an immune gap, which tends to weaken your heart.

Either old age or a bag taped over my head, though people tend to urge against the latter

Suicide, drug OD or heart attack or aneurysm.
The best case it'll be a heart attack or quick stroke death after getting over my demons. But those demons have utterly fucked my health.
If my body holds out against the abuse I inflicted on it then Alzheimers is a long shot possibility.
To be honest I'd rather go out by quick heart attack or aneurysm.

I’m only starting my sixth decade on this rock.
I fully expect to die in one of two ways:
In the resource conflicts of the 2030s and 2040s, as multiple worldwide crop failures due to chaotic weather brings widespread starvation to even first-world countries like Canada, and there will be people who will gladly kill me for what I’m growing in my backyard.
A preventable/cureable old-age ailment or incident of some kind in the 2040s of 2050s, as the healthcare system will likely no longer exist for anyone outside the Parasite Class by that point.
- I'm a little younger than you, and desperately hope I die before resource conflict wars start in earnest. It'll be like the great depression, only constantly getting worse, and with no end. Combined with global warming, millions will die from no yeat in winter, no AC in summer, on top of the no everything else. Life expectancy drops from lack of accessible dental care alone will be horrifying. At least wth no transportation, we'll be spared the worst of global pandemics.
  Man, I hope I'm gone by then. I feel horrible for my nieces and nephews, though.
  
  from lack of accessible dental care alone
  If you have genetically shitty teeth like I do, consider implants. Have bridges to limit the cost, yes, but choose permanents for longevity (snap-in bridges can more readily loosen the implants) and have multiple sections per side so that if a post fails, you can break off that bridge and still have teeth elsewhere.
  I’m aiming for four bridges per side. One pair for the molars and bicuspids on the left and the right, and another pair for the canines to the incisors in the middle. Total loadout being eight bridges across sixteen posts for the entire mouth. And at $4k CAD per post, it’s no wonder they call it “installing a Mercedes in your mouth”.

Assuming present trajectory, taken care of, but regretting being the last man out the door of the family I grew up with, I'm regretfully sure I haven't met anyone yet who will be there after those folks I'll miss have all gone.
- family I grew up with
  I appreciate the ambiguous yet honest and poignant phrasing here. Its reminiscent of how my mother is specified as biological most of the time despite the fact that I don't call anyone else Mom. It seems sad but I know plenty of people root for me in their own way and thats enough for me :)
  
  Honestly the way I see it, if you need to distinguish bio-family-members, something has gone horribly wrong, or you're adopted and doing a heritage understanding project

own hand or vehicle accident

Liquid nitrogen leak over a weekend.

Climate catastrophe

Heart disease most likely. I don't really exercise, and I sit at a desk when working.

Suicide (although it will get a pretty name like, "self-administered euthanasia").
Eventually my body or my mind will fail, or I'll decide that there's no chance that the world will ever improve meaningfully, and I'l remove myself from it.

I've got some pretty crappy, chronic health problems, so I'll probably kill myself when they get to be too much. Better that way than to endlessly degrade. But maybe I'll get lucky and euthanasia will be legal by then.
If I'm not lucky, my body will kill me before I get to it and I'll probably drown in my own lungs or die of some random infection (cystic fibrosis).
