Our liver. It trashes almost anything that enters our bodies, making medicinal chem research so difficult. It’s truly a marvel.
How fragile and how robust the human body can be all at the same time.
People have survived horrific trauma... getting their face blown off with a shotgun, knife to the brain.... yet at the same time, you bump your head just right and you die instantly.
Our ability to lie to ourselves such that we can alter what we believe to be true.
[Persistence hunting.](https://en.wikipedia.org/wiki/Persistence_hunting) Basically, we're really *really* good at endurance running. The theory is that ancient humans would just walk and jog after their prey until it collapsed of exhaustion or died. [Here's a Reddit post](https://www.reddit.com/r/HFY/comments/4akci3/persistence_hunting/) (from r/HFY) on the subject.
And it gets better. Basically the only animals that can keep up with us are horses and dogs. Which we domesticated.
we created "this". we are communicating to each other with keyboards we build, connected to computers we built, connected to an internet we built. if that doesnt impress you im not sure what would.
and as far as we know we are the only ones to do such things. anywhere. ever. we have found no signs of life outside of earth. at least not yet, im in the camp that believes there are other intelligent beings out there somewhere, but as for now we officially are the only ones. and nothing else on earth has mastered things the way humans have.
we are incredibly unique and advanced with what we have accomplished and built for ourselves, far beyond all other known life by a long long ways.
We kinda just switch to power-saving mode after like sixteen hours and nobody really knows why.
Our ability to sweat and run longer distances than other animals. Also brain plasticity.
Our heart beats from before we're born until we die. That's years and years of continuous work without a break. It's amazing anything can work for that long.
Man can be trained to master incredibly complex and abstract activities and fields of knowledge, such as quantum physics and relativity, paint and sculpt incredibly lifelike works, and sure, why not say the classic example - rocket science (engineering, actually).
All this know-how can be passed on and expanded, refined.
Humans are the only animals that have studied and tracked their evolutionary history.
The incredible capacity for love and kindness.
Yes there are awful people, and they're in the news constantly. But think of all the people out there fostering children without a home and without hope in their lives, but these total strangers open up their homes and take them in and care for them. Think of every person who finds abandoned animals on the side of the road and takes them in and loves them for the rest of their lives. Think of every disaster, where hundreds or thousands of strangers come together to do everything they can to help their fellow people. Think of teachers who have no budget and no help spending all of their free time and every penny they have teaching other people's children how to be decent human beings. Think of doctors and nurses who go days without sleep to care for other people.
It's wonderful. I love it, humanity is beautiful, and no matter how shitty things may seem, when it comes right down to it, people will always help each other out.
We threw some dudes at the moon, just because we wanted to.
