Live long and prosper? It's a lot simpler than you think, says Dr Chatterjee

Doctor Rangan Chatterjee is on a mission to spread the good and healthy life to the masses.

If every aspect of your life is the same in 10 years as it is today, would you be happy? It is one of the many questions posed by celebrity doctor Rangan Chatterjee in his first ever live show, Thrive. Sure, it looks trite written down - the sort of thing you might find in a fortune cookie - as I realise are most of the quotes I've typed into my phone by the end of the first half of his nearly three-hour stint. Consider it, though. Would you be happy?

To listen to Chatterjee - whether live or on his chart-topping podcast, Feel Better, Live More - is to submit to simplicity. His listeners (there are millions) aren't looking for groundbreaking medical advice or for remedies from far-flung corners of the Earth. When he touches on a topic like longevity, it feels approachable.

Chatterjee's renown dates back to his time on BBC One's Doctor in the House. He would visit a new family in each episode and live with them to identify how they could alter their lives for the better. His conversation with Jonathan Haidt - on the problems caused by phone addiction in teenagers - was the third most popular episode of any podcast in the UK last year.

Chatterjee is currently touring the country with Thrive, taking his mantras to the masses at £41 a ticket - the same cost to the NHS of a nine-minute consultation with a GP. The London leg of his show was held at the Lyceum, with over 2,000 people in attendance. "No one's here to see The Lion King, are they?" he joked.

It's not complicated
