              I had to live to sixty-three
              To see the crow in the cherry tree.

Also, do you know 'Counting in Sevens'?

[...]
Seven nines are sixty-three; seven tens are seventy.
Who would that old woman be?
She will remember being me,
But what she is I cannot see.

Yet with every added seven.
Some strange present I was given.
