Super-fruits. Antioxidants. Red wine? The list of things we're told to put into our bodies to boost our health and well-being seems to know no bounds. The fact is, health stories litter the national media like never before. But whether such foodstuffs actually boost longevity, among other health claims, is open to serious debate. What is not is that companies are making money out of them.

With people in the UK seemingly growing to riper and riper old ages, some might argue that we're developing a national obsession with our own mortality. Maybe health has become such a hot topic because more and more people are looking forward to an ever greater period of retirement? Then again, it could even be that, with church-going in decline, most people are living in far greater fear of 'the End'?

But what we'd like to know this week is this: what do you think is the one thing that contributes most to a long, healthy life?

• The Mediterranean diet?

• Would you say that food is more or less of equal importance to exercise?

• Maybe it is all in the genes and there's little we can do about it?

• Is it just a positive outlook on life?

• Could it be having lots of children and grandchildren?

• What about a private health care policy?

• Anything else you can think of?

• Or is it better to just relax and not worry about it?
