The Race Between Variants and Vaccines

All over the world, there are people who are living extraordinary lives, full of happiness and health – and with hardly any heart disease, cancer or diabetes.

Scientists now believe we can even reverse the symptoms of Alzheimer’s dementia, and in fact grow sharper and more resilient as we age. Sanjay is a dad – of three teenage daughters, he is a doctor - who operates on the brain, and he is a reporter with more than two decades of experience - who travels the earth to uncover and bring you the secrets of the happiest and healthiest people on the planet – so that you too, can Chase Life.
