Lemmy, what's the meaning, or point if you prefer, of life? I know 42, but I'm serious. Nothing lasts, everything is meaningless - are we just amusing ourselves until death?

I'm not depressed (at the moment, well maybe a little), just feeling philosophical.

Edit: the idea of this came to me because I was pondering why people fight so hard to beat diseases and live a few more years. What are they planning to do? Why exert effort just to be here longer when you don't have a reason?

Just why?
