Me, for example. I'm tired, and done and ready for oblivion whenever, but if I had children, I assume that I would change that view. That I would fight for every inch of my life because I had them to look after? But then, once they're old enough, would my life suddenly lose its meaning again?

Only curious. Just a thought. I'm not having children at the moment or anything. Don't get your knickers in a tizzy.
