I ate on a smaller island one day. Most of the island was owned by a German immigrant. He was 70 years old and he didn't look a day over 45. He had been there for 49 years or so. It's more than genetics. It's the way of life also.
I went to Santorini in May...what a place! It was easy to imagine staying there - the cares of the world wash away.
You have to wonder what this modern live has really gained us.
