Something's been on my mind as I'm studying evolution and I feel I need to air it out. The idea that having to work as hard as possible for your base nessicties and having that be healthy for a living creature is kind of bullshit. Usually, it's the animals that can gain the most energy input while outputting the least amount of energy that end up surviving. So really, there's nothing wrong with finding the lazy way to do something. So if we aren't getting what we need after working 40 hours a week, it's actually better for us to find a less demanding job. I hope I made my point well, but that's kind of my way of seeing it.
TLDR:
Being lazy is an evolutionary advantage.
