It's genes, good bone structure and posture Apart from that look after your teeth and hair (I don't care what anyone says, grey is aging).
Classic clothes but kept up to date.
I think having children in my mid/late thirties has kept my outlook younger.
I work very hard still in a full-time, professional job at nearly 62 so am not rested but my mind is active.
And finally, an easy life. No money worries to provide stress and anxiety and a life full of love.
People are genuinely surprised when I say I'm over 60.
Having said all the above I drink, love food, have late nights, don't exercise enough, enjoy the sun and use No 7 wipes to remove make-up and soap and water in the morning. I have bever used a moisturiser.
My final one is look after your feet, wear comfy flats that fit and have summer pedicures. There is no point looking a million dollars down to your ankles. If they aren't great, don't wear sandals.
My regret is not looking after my hands better. Never remember a bit of hand cream.
