People who have had some time to grapple with it are usually not so afraid of death, rather, they fear feeling insignificant, lack of a legacy, or that they have not made any a lasting contribution. I have noticed this myself and have recently heard it from someone else who has intimate knowledge of the subject.

Being in a web of friends and people who know you, and respect you, what you have done, this makes you feel significant. It makes you feel like you might have made a contribution.

Today was a day of this.
