Two thoughts from people who have been through it already, about aging and dying:
"Joy in old age. The thinker or artist whose better self has fled into his works feels an almost malicious joy when he sees his body and spirit slowly broken into and destroyed by time; it is as if he werein a corner, watching a thief at work on his safe, all the while knowing that it is empty and that all his treasures have been rescued."
- Human, all too Human
"All goes onward and outward ... and nothing collapses,
And to die is different from what anyone supposed, and luckier."
