(If we are talking about hunter gatherers, not poor exploited peasants)
We are certainly much healthier, with the little trinkets we keep in our houses.
The real point here, is a lot of people today don't realize how supported they are, with medicine and the trappings of modern life. The simple things I've listed are quite literally a wonder, but to the modern human, often it's not even considered a big deal.
Even in a rural remote areas of Canada or the US, you can just get in your vehicle, drive for half an hour, and then suddenly be surrounded by tens of thousands of products to make you healthier. A city dweller can walk for five minutes, and have the same.
No doubt. But I like to spend time in remote wilderness, so I do know what I have and do not have there. I definitely feel healthier if I am outside more often and can take care of various injuries myself, but if I would really need one, I surely would call for a modern medical helicopter and not go find some plants.
If you made it past age 5 as a hunter-gatherer you’d likely live to 50-60 years of age.
