The wonderful thing about age is that your knees don't work as well you can't run down steps quite as easily and obviously you can't lift heavy weights. But your mind doesn't feel any different.
I avoid talking before the youth of the age as I would dancing before them: for if one's tongue don't move in the steps of the day and thinks to please by its old graces it is only an object of ridicule.
It's not catastrophes murders deaths diseases that age and kill us it's the way people look and laugh and run up the steps of omnibuses.
