I’ve seen a living zombie hoard before, at a dump in Nicaragua where they lived. I was told they got high on sniffing shoe glue, which literally causes the brain to decay while they’re still “alive,” but they just shambled around in a big mob, seemingly aimlessly, with glue smeared under their noses.
Yea, work in and of itself is great. You have to do SOMETHING with your time every day, and doing something productive is extremely satisfying. Filling out spreadsheets for 8 hours with a 2 hour commute then going home to eat instant ramen in a noisy shoebox is slightly less satisfying.
