As someone who's coming to terms with their age and lifespan, this hits me hard. But I have nobody to rely on and have no connections. It sucks being a hikikomori with a disability, potentially forever stuck in poverty.
I'm not even that old yet, but I may not even live old enough to see my children grow up that much, if I ever have any. I may lifespan may have been cut short to live as long as the lower 10% of lifespans in my country and I may die before my mother, but on the bright side of life, I've already lived longer than 1% of all people and somehow overcame paralysing death twice, so that's something.
