"Sahlins' argument partly relies on studies undertaken by McCarthy
in Arnhem Land
, and by Richard Lee among the !Kung. These studies show that hunter-gatherers need only work about fifteen to twenty hours a week in order to survive and may devote the rest of their time to leisure.
Lee did not include food preparation time in his study, arguing that "work" should be defined as the time spent gathering enough food for sustenance.
When total time spent on food acquisition, processing, and cooking was added together, the estimate per week was 44.5 hours for men and 40.1 hours for women, but Lee added that this is still less than the total hours spent on work and housework in many modern Western households.

Hunter-gatherers also eat healthier diets
