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.

The lack of heart cancer might be more complex than the OP imagines:

   I greatly resent having to be a biological organism and subject to all the poor engineering and design decisions that entails.

The first word of that sentence implies its absurdity quite beautifully. She resents, therefor she is.

And then this:

  Brains. After you reach adulthood, neurons don’t divide. If some of your neurons die—which happens every day—then they’re gone. If you get a brain injury, the other neurons will try to “learn around” the injury, but the neurons themselves are never replaced.

We need more neuroscience in schools! This summary is technically correct ofc, but to imply that the brain is missing some obviously-better option is absurd. We're meat that thinks, y'all; it's far from crap.

> Evolution decided the good outweighed the bad, and I expect that evolution was right.

We can expect evolution to do the right thing for the genes. Not for us.
