Don't forget that until they were forced into marginal land, hunter-gatherers didn't actually have to move very far or fast, and unless you simply couldn't walk at all, you could still gather, watch the kids, do the cooking, etc. Oh, and consider how useful the physically crippled are to a farming community that already has as many smiths, tanners, etc., as it can support. The situation is just as grim as for a hunter-gatherer. > Medieval child mortality in Europe was up to 50% by age 6.

Again, all this is not as bad for hunter-gatherers as it is for farmers - in spring there are still animals to hunt. They may not be in the best condition, but they'll do.
