What a lovely set of replies and thank you for the welcome.
I'm not sure it always hits that chord - feeling younger inside. Referring to my attitude at work a colleague recently said to me, "If I didn't know your life I'd put you at least 10 years younger." That would make me her age. It felt churlish to say "Honey if I didn't know yours I'd put you at least 10 years older!". Horses for courses I guess. But I'm not ready to hang up my boots and sit on the sofa of life quite yet
