I am in awe about how wonderfully engineered by evolution the body is. E.g., what we are able to do with it and how it heals itself when we have an injury. Sure, many people would not live long without external intervention, but many others would. I still want to see the robot that can survive 80 active years without maintenance.
Well, we do at least have to eat enough food and sleep ~1/3rd of our lives. That's kinda maintenance
Compared to most animals that spend their entire day foraging for food, it's not too bad. Adapting to eating dense and very nutritious animal flesh is a great time-saver, and as we didn't evolve long fangs, we had to learn to use tools instead, and the rest is history. (mixing cause and effect here for dramatic purposes)
I think learning to cook food was likely a greater benefit. It's like we externally expanded our means of digestion.
I watched a Ted talk where the speaker suggested our large brains with their high energy consumption would not have been possible were it not for cooking.

quite the delightful maintenance too
that's absolutely maintenance, without it you have a total system failure in a week
The human machine doesn't just survive without external intervention, it actually gets better at being a machine. Speed, endurance, power, coordination... all improve with usage.
until you get old and goes the opposite direction
When you watch those sci-fi shows and folks have nanobots implanted in them that heal wounds really fast or do other cool things I can't help but think in many ways we already have that technology we just need it to do more, faster as our brains and ability to create things have outpaced the rate of evolutionary change.
Humans don't last long without topping up their fluids and consumables.
no you don't
Well, so much for that discussion.
The human body can't survive 80 active years without maintainance. They take drugs, they see the doctor, etc.
What did people do 500 years ago?
Die as a child at alarming rates
