Throughout evolutionary history, individuals who engaged in effortful foraging, hunting, and caretaking were revered, suggesting a biological basis for valuing effort.

“Throughout evolutionary history, there's no question that we revered people who were willing to go out and forage and hunt and gather and caretake in ways that other members of our species probably found exhausting and probably would have preferred to just put their feet up or soaked them in a cool stream rather than continue to forage.”
