It is not about striving for immortality, but about accepting mortality.
Accepting your own mortality is like eating your vegetables: You may not want to do it, but it's good for you.
As a culture, we are not comfortable with mortality. We do not accept it the way other cultures do. We cling to youth, and we don't want to die. It's like, 'Well, too bad, we do.'
It is the mark of an educated mind to be able to entertain a thought without accepting it.
I had a stick of CareFree gum, but it didn't work. I felt pretty good while I was blowing that bubble, but as soon as the gum lost its flavor, I was back to pondering my mortality.
