Some[1] do invest, others don’t. Personally, I see myself on the poor side, rather than the rich side and what I care about is having a good life however short it is. Family, friends and adventure. I don’t believe in the afterlife in any form and I wish I could live forever with my loved ones but I’ve also accepted it’s natural to die. Maybe one day we will overcome death and we will live until the heat death of the universe. Meh.
