“You are old Father William, the young man said,

And your hair has become very white,

And yet you incessantly stand on your head,

Do you think at your age it  is right?”

 

“In my youth, said the sage, as he shook his white locks,

I feared it might injure the brain,

But now that I’m perfectly sure I have none,

Why I do it again and again.”

– Lewis Carroll
