It seems like a simple question, right? Think about it. Do not think about what you are leaving behind!!! That is a different question!!! I mean, are you afraid of death? Just death.
I think most people are afraid of time, not death. Not having enough time to do what they want, see what they want, etc.
In the words of Albus Dumbledore, "To the well-organized mind, death is but the next great adventure."
So, are you?
