“They soon stopped being ten years old. But whatever age they were seemed to be exactly the right age for having fun.”

“90/93-year-old Jacob wonders as he gazes at his aged reflection, 'When did I stop being me?”

“Peter, you're twelve years old. I'm ten. They have a word for people our age. They call us children and they treat us like mice.”

“The things that stop you having sex with age are exactly the same as those that stop you riding a bicycle.”

“...it is so silly of people to fancy that old age means crookedness and witheredness and feebleness and sticks and spectacles and rheumatism and forgetfulness! It is so silly! Old age has nothing whatever to do with all that. The right old age means strength and beauty and mirth and courage and clear eyes and strong painless limbs.”

“Old powers waken. Shadows stir. An age of wonder and terror will soon be upon us, and age for gods and heroes.”
