I understand why you may not understand it as its truly doesnt make sense
(But there are many things in life that doesnt make sense unfortunately, especially human mind

)
To me im more concerned about the chemical pneumonia due to intoxication from throwing up, not only about the throwing up itself
So i dont specifically speak only about throwing up but im speaking about the fear of dying process until death and why people search for the most preferable method/the least painful
Even a chronic incurable debilitating disease patient like cancer, interstitial lung disease, MS or ME or lupus, etc
Whos living in hell, tortured in excruciating pain all over the body+mentally for the rest of life, still afraid of dying/suicide and cant just throw themselves/jump to die
Its even worse because theyve experienced the pain of dying and traumatized by it.
Besides people have different: strength, personality, thinking, stress tolerance level and pain sensitivity, etc
(Thats why not everybody capable to pass the test into military force)
It doesnt always mean if someone cant throw themselves under the buss meaning their life isnt bad enough
Or if their life is bad enough they should be able to throw themselves under the buss
Not to belittle anyones feelings, but I find it really hard to understand how someone who is wanting to die and is prepared to end it all can baulk at a method because they might throw up, "because throwing up is horrible".
I mean if your life is that bad and you don't want to be here any more, then surely throwing up at the end is nothing?
If you decide not to do it to avoid throwing up and live for another 30 years - well I can bet you with pretty much absolute certainty that you'll throw up at least once in those years through illness.
It makes no rational sense at all.
Any method might involve throwing up, whether you get hit by a train and smashed into pieces, jump off a cliff and throw up on the way to the rocks, drink nembutal, hang yourself, inert gas asphyxiate yourself, or anything else - even dying of old age and/or illness.
Death is not flicking an off switch. Something has to happen, and throwing up is pretty much nothing.
Isn't it?
