Angela Rippon and Dr Chris van Tulleken travel the world in search of the latest science that could help us all stay young and healthy for longer. They investigate the best ways to help both our bodies and brains age better. Up first is the body, and Angela travels to Germany to join a groundbreaking study which reveals the exercise that holds off ageing the most. Chris visits America to find out about the unexpected diet that can add years to our lives. And in Ecuador we meet a seventeen-year-old who looks like a child to discover how scientists hope he may hold the key to preventing the diseases of ageing.
Horizon investigates the idea that the best way to lose weight successfully is a personalised approach, diets tailored to our individual biology and psychology. In a groundbreaking experiment, Dr Chris van Tulleken and Tanya Byron join a team of experts to put 75 overweight volunteers on diets designed to tackle the specific reasons why they eat too much. The volunteers are put through a series of tests at a residential clinic to understand how their genes, hormones and psychology influence their eating behaviour. They are then put on the diets the experts believe are best suited to them. Can science succeed where other diets have failed?
The world stood in fear of an emerging new disease that threatened to kill millions. A new flu variant H1N1 had arrived. If this latest pandemic has taught anything, it is just how little is understood about the invisible world of viruses. But that has not stopped scientists trying. Horizon follows the leading researchers from across the world, who are attempting to unravel the many secrets of viruses to understand when and why they kill.
What's your idea of the perfect birth? Do you want every medical intervention known to science or do you want to go it alone, without the help of a doctor or midwife? And what about after birth? Perhaps you'll hang on to your baby's placenta and carry it around with your newborn until it dries and drops off naturally? Or maybe you'll decide to eat it by whizzing it up into a smoothie? This film follows four pregnant women all making very different choices around their births, all determined to do it their way." 37-year-old Jo plans to deliver her baby completely alone on board her barge, without the assistance of any medical professional. By contrast, 34-year-old Anna is opting to sidestep the pains of labour and book in for a c-section at the Portland Hospital in London. Anna wants all the medication available and she doesn't want to feel a thing. There are plenty of unusual plans for after the birth too. In Devon, 33-year-old Lisa plans to lotus birth - she'll leave her baby's umbilical cord attached to its placenta and she'll keep it fresh by dusting it with salt, rose petals and lavender oil. 35-year-old Kati from Manchester is going to whizz her afterbirth into a smoothie and consume it over a number of days. She hopes it will help her stave off post-natal baby blues and bounce back as quickly as possible. Fending off bewildered looks and concerns from friends, family and medical professionals, each woman is going against convention to have the birth she wants. There are free and frank discussions between mums and daughters and decisions to go against medical advice. So does breaking with the norm and sticking to your guns pay off? And what really is the perfect birth?
Why do we sleep? And what does sleep have to do with memory, trauma, and our emotions? From fruit flies to whales, virtually every animal sleeps. But why? Why do we need to spend nearly a third of our lives in such a defenseless state? Scientists are peering more deeply into the sleeping brain than ever before, discovering just how powerful sleep can be, playing a role in everything from memory retention and emotional regulation to removing waste from our brains. So why are we getting so little of it?
