What scares me it that I've been to locations where I did work and realize that I had been there 25 years before. Trees have grown, house colors have changed, etc. but it's spooky to realize that I was there a quarter-century ago.
The service company that I worked for in the 1980's had a strict policy that we place advertising stickers on the panel as part of each service call. I always marked mine with my initials and the date. Now I know that I am getting old. I saw my own handwriting that was 22 years old on a panel last month.
