Hit midlife? What do you want to do with the second part of your life? Immunologist Dr Jenna Macciochi wonders that despite living longer now, we’re not necessarily living as healthily or as fully as possible during that time.


In this chat with Fearne, Jenna talks through how we can keep our bodies as resilient as possible as we age, so we have the strength to properly embrace the fun parts, and better cope with the shit parts.


Jenna breaks down the science of immunity and its relationship with ageing, but there’s no mad biohacking here, just simple advice to make sure your body is a comfortable home to live in: we’re talking food to support your gut microbiome, oral hygiene, and reducing stress. Plus, there’s chat about how your social life is affecting your immune system! (Spoiler – you’ve got an excuse to hang out with your mates more!)


Jenna’s book, Immune To Age: The Game Changing Science of Immune Health, is out now.
