Marcus Berkmann's funny, instantly recognisable description of middle-age in 'A Shed of One's Own' struck a chord and turned it into a bestseller. Now he realises he has entered a new age category: the Young-Old. Well, the body continues to provide challenges (every group meeting seems to begin the dreaded 'organ recital'), and the bank balance may not be doing too well either - but it's certainly not all doom and gloom. You have come to terms with your deficiencies and eccentricities (although your partner may not); your Fear of Missing Out has become Joy at Staying In; you have embraced the notion of the Power Nap - and though you're not going to embark on a course of 'mindfulness' you nevertheless recognise if living in the moment also includes walking to the local for a pint with an old friend then you'll sign up for it after all - you could call it 'beerfulness'.
