In the foreseeable future we will raise life expectancy further and further. It is now easy to replace many body parts and rejuvenate the body in many ways.

So maybe we can rebuild and regenerate our bodies for hundreds of years - but what about our minds?

Most people’s minds already go down the drain in their 40’s without physical “defects”. And when we live longer we need to constantly learn new stuff - you can’t play dumb grandpa if you live 200 or more years. You need to learn and adapt.

And what about the emotional strain of a long life? How much pain, idiocy and trivia can you take before you loose your will to live?
