Yeah, maybe the only possible way to live that long is to live on a secluded island with pure air, water and organic food, without wars, stress and worries of the modern world. But in that case why live 100+ years if life goes past you?
LOL.. Can you even imagine? A life without cable TV, internet, FaceBook, Instagram, Twitter, Skype, WhatsApp.etc. Can you even survive for one week on such a location? Anyway, what is the point in living up to 100 years, if you can't enjoy your life?
In order to survive in such a place without the benefits of civilization, one must prepare for the fact that one will have to extract food, live in the open air and love loneliness very much.
