> One broken limb or scratch would likely mean you're not going to live much longer.

Yes, people back then suffered a lot of broken bones, even fractured skulls. But just like their bones tell that story, we also know that they often survived those injuries and their broken bones (and even skulls!) healed. People lived in groups and cared for injured.

Also a scratch is probably not going to kill you. It could, but likely won't.

> Also, children were easy food, and women definitely died in childbirth.

Going after the children of an organized group of apex predators is probably not going to end well for the attackers.

And yes, sometimes women died in childbirth, but not that often (otherwise you wouldn't be here to type that). Also there's still a decent risk of that if you live in the US.

> Scurvy wasn't just a disorder that was tied to long ship travel.

Extremely rare on a hunter-gatherer diet. Our ancestors lost the ability to produce their own vitamin C internally millions of years ago, because they just didn't need it. Most other mammals still can.

> Mosquitos carried pathogens

Human-adapted mosquitos hadn't evolved to the degree they have today, so bites would have been much rarer, but pathogens causing fun diseases such as malaria did already exist.

> the other food sources were also of random quality.

You mean the food sources we evolved to consume? Are you talking about parasites? Most of the nasty ones really only started becoming an issue when humans gave them breeding grounds in their settlements.

> If you were born with poor eyesight or hearing, too bad.

I guess?

> I could keep going on,

Please don't. You are clearly just guessing and making stuff up as you go.

That said, of course hunter-gatherer life was much riskier than modern life, but that was just their normal. Hedonic adapation and all that.
