Gloria Hunniford's beautiful daughter, Caron Keating, had cancer for 7 years before she died aged 41. Gloria believed that positive thinking helped extend her life:

Caron lived by the book 'The Power of Now' i.e. living in the moment and being really positive all the time.

Gloria described what they spoke about: "We never talked about death - only about life and I believe positive thinking can extend life…. but everyone's cellular make up is different and everybody reacts differently. It can't be a pattern for everybody

Dermot continued: "I don't believe positive thinking can cure all ills but, with a multi-dimensional approach, you can help your doctors to treat your illness.

"There is lot of skill involved. Just like an Olympic athlete, you don't rely on your coach to win the gold medal for you. You have optimum nutrition and exercise plans and a sports psychologist to support you.

"You don't just go to the coach and say 'I'd like to win the gold medal. I'll check back in next month to see how I am doing.' You'd go through a whole process and one aspect of that would be a positive mental attitude.

"Saying 'positive mental attitude' is a bit like saying football is about kicking a ball. It is an acquired skill and there a lot of techniques we go through in the book."
