I stick around because (like some other people here) I want to live to see or even better help discovery the set of rules that underly the universe, see the stars even if just in photos, see what humanity is capable at its best, create anything that comes to mind, and learn everything I can. If the reason I dont want to live is the world around me (which it is) then I'd rather go out fighting, trying to change things rather than giving up outright (as a sidenote I wish someone created a place for people like this to meet and converse I see y'all scattered around the place but I can't find a singular congregation spot). I mean I have what could either be classified as very well thought out delusions of grandeur or long term plans for a sort of immortality and if there's the slimmest chance I can achieve that then I'm gonna shoot for it, and if I die trying then I get to die knowing I contributed to science in some hopefully big ways. So in summary I live to spite the world we live in and for the admittedly astronomically low chance I achieve my insane goal as the reasons for not living all relate to not having enough time and being restrained to a material world. Writing it out loud it's quite convoluted.
