People in the wild don't hunt elephants to survive. They survived pretty well for ages, they climb for honey, find smaller animals. It's not easy but it seems most humans are capable of it. I'm pretty sure the deal is worth it. The amount of satisfaction in apt usage of your senses and body is quite immense. I suffer daily due to insufficient stimulation (to the point I volunteered my time for truck unloading) both physical and intellectual. And if you look at half the population, you can probably read that on their face too.
