I have asthma and I couldn't serve my country in the service
I have several friends who unlike me were either drafted or joined the armed services. Many of them have died.
One of these friends is buried in a nearby cemetary beside his mother and father. My friend was a Vietnam vet and his father was a veteran of WW2.
Since I couldn't serve my country as a soldier I try to make up for it by placing flowers and flags on my friend and his Dads graves.
When they fade I replace them.
