Yes, we can repair machines. And to some extent - and in the future to a further extent - we will be able to repair our bodies. But that's not the near future.

> give me the indefinite lifespan and I'll take my chances with the boredom and accidental death and brain overflow and collapsing society. Cause I'm sure all those things are bad but guess what, it's better than being dead.

The reality is though, that chances are much better than even that those things will not come to pass in our lifetimes, or even in our grandchildrens lifetimes.

So in spite of it being 'better' than being dead, chances are that you will die. What's so hard about it?

There are billions of data points (all the creatures that ever lived have died, with the exception of those that have not yet lived long enough to outlive their natural life span) and there isn't a single one that lived longer than 1500 years (an Olive tree, if I'm not mistaken).
