Why the instinct to survive?

[PerfectRecall17]

Why all the effort if all you are going to do is eat, sleep and shit anyways?

Why? No reason. It's all pretty pointless.

But it's a process. We only do these things because it's in our genetics to care. Otherwise we'd have died out long ago.

So I suspect the answer lies in evolution.

Note how that while most of us realize that it's all pointless, we go on living our lives anyway.
