Dame Joanna Lumley is famed for her vigour and youthful energy – something that eludes many of us in our 50s, let alone at 80. So what’s her secret? Quite simply, ‘doing things’ and keeping moving. ‘I’m busy, busy, busy,’ she says. ‘I don’t have time for gyms... I tend to stay fit by doing things and eating well.’

Joanna has previously talked about doing things with ‘vigour’ – whether that’s cleaning, gardening or taking the stairs. In an interview with My Weekly magazine, she explained: ‘I don’t go to the gym but I do stuff with vigour, such as housework, gardening and going up the stairs two at a time.’

She also believes that her vegetarian diet has helped her long-term health, saying this is the reason ‘I’m still firing on all cylinders.’ She adds: ‘I believe we should all eat much more vegetables and much less meat.’

Joanna gave us a further glimpse into her diet, speaking to Nick Grimshaw and Angela Hartnett on the Dish from Waitrose podcast. ‘I like raw things very much. I like salads and stuff,’ she said. What’s more, she thinks prioritising veg has benefited her hugely. ‘I do believe that not eating meat holds back the ageing process. But if vegetarianism is not for you, so be it. My husband Stephen isn’t a veggie and he’s wonderful.’

Then, there’s her moderate attitude to alcohol (which couldn’t be further from her Ab Fab alter-ego, the Champagne-guzzling Patsy Stone). Dame Joanna shared in an interview with Woman & Home that: ‘I try not to pop the first bottle of Champagne until after midday. I don’t always succeed. When I take it out of the fridge and it’s got my fingerprints on it, I think, “How much harm could one small glass do?” Truthfully, I’ve never really drunk much. I can’t stand feeling woozy and I can’t bear drunken people, so I’ve never gone down that [route]. I have a glass and that’s it.’

And her healthy approach is something we should all be aiming for as we age. ‘It’s not about denying yourself,’ says Dr Hannah Burrage, lead GP, Kry Livi. ‘It’s about knowing your limits have shifted and choosing to enjoy that one drink properly, rather than several that you’ll feel the next morning.’
