Death is not the enemy. Age is not the enemy. These things are inevitable, They happen to everyone. But what we ought to fear is the kind of death that happens in life. It can happen at any time that you are going along, and then, at some point you congeal. You know, like jelly. You’re not fluid anymore. Your solidify at a certain point in your life and from then on your life is doomed to be a repetition of what you have done before. That’s the enemy.
