Recently, Chinese scientists announced they had discovered a way to help people live to 200. Commentators queried whether or not anyone would actually want to live that long. After all, is living about longevity or quality of life?

A current BBC series looks at people who live long, healthy and active lives.The series attempts to understand and convey to viewers how one goes about living a long, healthy and happy life. There are fundamentals and commonalities in the behaviour of those who live long and prosper. Longevity and happiness are states of mind actively cultivated day by day. Eat well but in moderation. Exercise regularly. Challenge yourself. Have fun. Be active mentally and physically. Sustain relationships and don’t be reluctant to form new ones. Love and be loved. Be optimistic and realistic. Longevity isn’t just about being alive, its about happiness, fulfilment and a sense of purpose.
