Fair enough. To be honest though, I had 1909 in my head for the Wright Brothers (incorrect!) which would have put him in his 30s.
My grandfather, Pa Pa Joe will be 91 next July, earlier today we were outside shoveling snow! He is quite an amazing guy, can fix anything but only has an 8th grade education because he had to leave school at 13 to work in a leather tannery to support his family when my great-grandfather died. He remembers the troops coming bank form World War One. I love him very much!
