Childhood itself is scarcely more lovely than a cheerful kindly sunshiny old age.
I think it's your mental attitude. So many of us start dreading age in high school and that's a waste of a lovely life. 'Oh... I'm 30 oh I'm 40 oh 50.' Make the most of it.
But an old age serene and bright and lovely as a Lapland night shall lead thee to thy grave.
The lovely thing about being forty is that you can appreciate twenty-five-year-old men more.
