What an inspiring story. This makes me really teary-eyed. He is an outstanding soul and Peggy is very lucky to have such an amazing father.
I do think though it is another generation. You don't find so many people like him anymore, who are willing to sacrifice part of their lives for someone else, who live in their communities and actually care about the bigger picture, not just themselves.
My Mum was born in 1938, also like that, very selfless and hard working. She has seen so much hardship, in bomb shelters as a toddler, queuing for bread and basic necessities, etc. Her generation and before her, they seem so much more hardy, a real get-on-with-it attitude.
