Maybe not just because they die - to the extent there's non-hunting activity done by men, you'd expect it to be done by older men (=time to learn skills) who aren't the best hunters.

I dont know enough about this area but if youre not a good hunter in a hunter-gatherer society you're pretty screwed right? It's not like there are that many other career options surely?

Data for that graph comes from two societies, both of which aren't actually hunter-gatherers but forager-horticulturalists doing some hunting. Here's caloric production per day + time spent from the paper that data comes from. Further, one of the societies hunts with shotguns.pic.twitter.com/1Sie4XcC16

So time spent hunting in those societies peaks at 25 and actual caloric production peaks about 30-35. The loess smoothing in the graph
@DegenRolf shared is also misleading because you can't see how many data points there are. Unlikely there was actually anyone 70yrs old in sample1 reply 0 retweets 6 likes -

Alsi, I actually have studied a lot of papers about hunting expertise among hunter gatherers, and the rule is it doesn't peak before 40.

That's not a rule. Here is the Ache data (which is cited in the excerpt you posted). Peak is mid 30s in the 1980s. And again, this is return rate, time spent hunting and actual caloric production not included.pic.twitter.com/oBucDLsDe1

I have looked up all studies on the subject. There is agreement that hunting success doesn't peak before 40 On reading tracks: https://plus.google.com/101046916407340625977/posts/AEmXeeBuQYP … Here is the classic on hunting age https://s3.amazonaws.com/academia.edu.documents/46603755/gurvenetal2006JHE.pdf?AWSAccessKeyId=AKIAIWOWYYGZ2Y53UL3A&Expires=1528311839&Signature=sOmz3MqMtjZw%2BwSEbFP3UxUd9A0%3D&response-content-disposition=inline%3B%20filename%3DHow_long_does_it_take_to_become_a_profic.pdf …pic.twitter.com/mrc78pbXb0

Literally the only society referenced in that excerpt that are actually hunter-gatherers are the Ache, the rest are primarily horticulturalists who sometimes hunt. And I just showed you the Ache data showing that *return rate* peaks in mid-30's.

Other sources I read say that for some of the more difficult to hunt prey animals, peak age is even higher.

Replying to @DegenRolf @hbdchick and
Peak age *for what*? Return rate? That metric in isolation makes no sense. Is someone who spends two hours per day to get a kill a "worse" hunter than someone who spends 20 minutes a day hunting and gets a kill once every five days?
