We are created by sperms and ova as a means of making more sperms and ova. Once that's done, we're of no further use - except, as has been pointed out above, to nurture the next generation until they're old enough to manage on their own.

Accepting this gives one a remarkable sense of freedom, once the children have moved out. If you're one of the lucky ones whose children do move out, at the appropriate time.
