Lukas --
Thanks for sharing the video! It seems like the secret is enjoying what you do. After all, if you're not having a good time a long life can feel interminable. In some of the research that I did, one of his sons chalked his long life up to good genetics too, noting he didn't eat particularly well and had smoked until he was fifty years old.
I'd love to get away with that too!
Cheers & all best --
