I am 68! My OH will be 70 in two days! It suddenly dawned on him a few days ago and he was genuinely shocked!
My Mum was 29 for years and none of us questioned it.
Her Grandma lived to be 99 and, according to my Granny Mac, still rode a bike and could thread a needle!
Two of my lunch friends are in their 90s and enjoying life to the full. One puts the rest of us to shame with her yoga and keep fit sessions.
