I think the most viable thing to do would be to put your money towards building a geothermally powered unground habitat that is close to a large water source, and have a really good water purification system to filter it.
Also possibly use fibre optic cable to funnel sunlight in to grow plants which hopefully produce food and oxygen. Although safer bet would be to have enough power for internal ultra violet lighting and be able to split water molecules into oxygen and hydrogen, who knows if we'll somehow managed to block out the sun as well.
I've been thinking about this for a while, if anybody can lend me some large scale industrial excavation equipment, I'd really appreciate it c:
We'll probably become a big brother 1984 type fascist society at some point where I'll be sent to reeducation prison and they'll make me forget what retirement is and convince me to volunteer to a corporate labor camp until I die.
My plan is working til I fall over or reach 75, which is the new 65 according to some of our politicians, and then off myself, cause I never got the chance to save something for retirement due to circumstances.
After an oil crisis, cold war with nuclear threats, financial meltdown and assorted wars and famines I'm convinced things keep on going and on average do a slow deterioration with the occasionally bump and panic.
the only really sensible retirement plan is building a community that supports each other, become the neighbourhood grandma who everyone loves because she bakes pies.
you can have as much money as you want, if no one else cares about you you'll still be miserable and probably die in your home.
I'm in my 30s, and pretty much just work and go home. I've got no hobbies outside the house and have never bothered pursuing a relationship. No chance in hell I'm making it to retirement age. I figure the stress of my lifestyle will grind away at my will to live and I'll just stop eating at some point.
