Right, and I'm saying that the landscape has changed enough that many of the behaviors and characteristics we evolved back then, are maladaptive today; just because most humans happen to have a certain trait, does not mean that others should hold that trait sacred and kowtow+mold themselves to it. There are other examples, too; ones with even fewer exceptions. Our minds and bodies both help hoard energy; that trait-set was useful when animals were difficult to hunt, but today it just foments carb-poisoning, obesity and a raft of other pointlessly energy-efficient design tradeoffs. (The modern world is so much more energy-abundant than the ancestral landscape, yet we can't actually make use of anything past ~8 MJ a day for anything but high-endurance physical exertion. A human brain is like a Pentium II hooked up to a 500W PSU.)
