Showing as part of BBC Wales's Live Longer Wales season. There are more 100-year-old people in Wales today than ever before, but our centenarian count is still lower than the majority of western countries. Why is this, and what can we do to make sure that we too live long and healthy lives?

In How to Live to a Hundred, Welsh-Italian cook Michela Chiappa attempts to discover the secret recipe to longevity. It is a colourful and insightful journey that takes her from her home town of Merthyr all the way to the Italian island of Sardinia - home of the longest-living people in Europe - and back to the Welsh valleys again. Mixing food, lifestyle and science, Michela meets some incredible Welsh centenarians - each with their own theories and tales to tell about why they have lived so long.

She visits Wales's leading longevity expert, Professor Burholt, director of the Centre for Innovative Ageing in the College of Human and Health Sciences at Swansea University. Then she heads out to meet Europe's longest-living community: the people of the Ogliastra valley on the Italian island of Sardinia, where living to 100 is a surprisingly common occurrence. What she discovers and brings back to Wales is a surprising recipe for longevity.

A warm and engaging celebration of good food, good people and good living, How to Live to a Hundred offers a compelling insight into living a longer, healthier life. Show less
