I started working in the "adult" world when I was younger than most. Most of my customers were at least a generation and usually more older than I was. Given that, I have had an unusual view of mortality and how long people are remembered. Many of those people were important men in their time. You are correct. Once your own contemporaries are gone your trail fades quickly. We will be lucky if anybody other than a rare relative will know we were here in 50 years after we leave. I must admit that thinking about all of those folks and how long that many of them have been gone does make me pay more attention to the passage of time. I was a young man once, now not so much.
