Dorothy Custer is the definition of gumption. Listen to her tell the story of how she met her husband, then at 2:10 she reveals the secret to long life (btw, it's the cutest thing ever).
“For me, it was hitting rock bottom and it was a wake-up call. Honestly, it was the day that my boyfriend and I had broken up and it had nothing to do with him. But it was just the moment that I was really broken and I was really upset."
