When I was a kid in the early 50's in my home town on Memorial Day (often called Decoration Day back then) they had a ceremony where they took
pictures of local vetrans. They would do the Korean war vets, then the WWII vets and so on. There were 2 vets from the Civil war. They had to be close
to 100 years old. My grandfather told me that they had lied about their age to get in the military.
