Amazing to think of all the changes they've seen over the years. Growing up in Ireland, I met one WW1 veteran as a kid, my friend's Grandad. He actually served in ww2 as well being a career soldier in the British army ending up as a warrant officer. He taught us how to drill and told us the story of how he shot down a plane once.
Actually both my Grandfathers served in the British army in WW1 but both had died before I was born.
Sad to think they're nearly all gone.
