To be honest, I started feeling like that in my late 20s and stopped drinking after my 30th birthday. I’m afraid all those late nights and junk food in your 20s take it’s toll. You are basically paying off the debts your younger self has piled on you.

The good news is that it is reversible - I just had my annual checkup and all my blood work is in the green and the numbers are trending in the right direction (although I was told to eat more oily fish, which I don’t like).

All the improvements I’ve made have been me pretty much me making it up as I go along but it is starting to pay off. However, there’s now better advice around and if I could suggest just one thing, it’s the radio show of the same name on Radio 4. I can find his tabloid pronouncements a bit suspect but the radio show is spot on. The latest episode was an inflammation special and if I could suggest just one episode of Just One Thing, it’s that one. Inflammation is increasingly being seen as the root of a lot of age-related issues and you can do plenty about it - eat better and move more.

I see the next episode is on taking Vitamin D and, for anyone in the UK, that’s vital as we don’t get enough sun for 6 months of the year and those, like myself, who are so pasty they burn under a Full Moon, so wear sunscreen much of the rest of the time then it’s needed all year round.
