Designed?

This is my Eureka! (moonshadow duo) Which will be my home for a couple of weeks.

We're all designed to fail, aren't we. When our lifetime is over, we're dead. There seems to be no living animal that has no expiration date. Our design isn't optimal.
Maybe future models of the human being has a much longer lifetime.

But actually it isn't about lifetime, it's about efficient use of our time and the perception of time. Look at a one day fly. It uses time efficient though it's real time is not long. For humans 20% of lifetime is meant for childhood. Does a fly, a bee, etcetera need that percentage. They're much advanced by evolution. Everything goes faster when you're small. Those little animals flew around long before dinosaur walked around. They were evoluated to what the presently are.

I don't think about a plan, a grand Masterplan or something like that.
In time we learn more and more about evolution of material and there will be a time that humans know about the evolution of the brain and the mind, what humans make human. And this accident is the most wonderful thing which could ever happen.
