The amygdala saved my life once, when I was nearly hit by a car and reacted before my neo cortex could respond. However, the amygdala usually causes tragedy. I am still haunted by the account of one father, who came home and his daughter wasn't responding to his calls. He got concerned, got his pistol and went to her room to see what was wrong. She was hiding in her closet and jumped out to scare him and before he had the chance to recognize her voice and face, the amygdala took over and shot her. She died. Now that I think on it though, how paranoid does he have to be to grab his GUN before just walking over to see if she is ok?

Its more dangerous due to the size of the human brain as I understand it. Maybe we should have evolved as marsupials.

It's because teeth have nerves to sense if something is wrong but cancer cells are just normal cells with an extra fast spawn time, no nerves to detect that, maybe if that growth starts pressing onto a nerve there would be pain involved

The Rise Of Mammals does a really good job explaining this! Basically, one of the great innovations of mammals was the development of teeth with opposing surfaces, for maximum chewing efficiency. Sharks can loose teeth and replace them constantly because they don't chew, they just grab and rip, so it doesn't matter how their teeth meet up. If a human's molars did that, our regrowing teeth wouldn't contact each other the way they need to for us to eat. Elephants do a kind of conveyor belt where only a few of their massive teeth are in their jaw at a time, moving forward as they wear down and eventually falling out to make room for the next set, but once they wear out their last teeth, they die shortly after. Grass-eaters like horses usually have extremely tall hypsodont teeth that gradually erupt out of the gums as the top wears away. And rodents have their always growing incisors. But with mammals, once they actually lose an adult tooth, it's gone.

"The human knee. It is a nightmare of an engineering kludge.

Two rods, the upper and lower legs, balancing on top of each other, supporting the entire weight of the human body. And the only thing that keeps them from bending backwards? A tiny, free-floating thin half-dome of bone not attached to anything at all. And what keeps them from collapsing entirely? A mass of unhealing cartilage and some muscle fibers.

8 pounds (!) of precise force can snap the knee from the side, permanently crippling a person.

It is a ridiculously fragile, slapdash evolutionary kludge of the sort that could only be selected for in a species expected to live no longer than about 25 years.

Only - humans live a lot longer than just 25 years now, but the knee has never changed."

The maximum lifespan for a human tops out at around 125 years under ideal conditions, and that figure hasn't moved much since the Stone Age. The reason we have this narrative about people not living past 25 is because of the confusion with average life expectancy at birth, which includes high infant mortality and childhood deaths into the average.

If that "someone" is no longer living the hurt intensifies.
