Well isn't that just the 64 million dollar question. How to Stay Young returns for another series as Angela Rippon and Dr Chris van Tulleken investigate the latest experiments and research that could help put the brakes on the ageing process. In this first episode, 51-year-old Patrick Luckie sees for himself how much damage his diet is doing to his heart, and 47-year-old Jenifer Tutty uses a radical new technique to cure her insomnia.
