Seven years and six months!" Humpty Dumpty repeated thoughtfully.

"Seven years and six months!" Humpty Dumpty repeated
thoughtfully. "An uncomfortable sort of age. Now if you'd asked MY
advice, I'd have said `Leave off at seven' -- but it's too late now."
"I never ask advice about growing," Alice said indignantly.
"Too proud?" the other enquired.
Alice felt even more indignant at this suggestion. "I mean,"
she said, "that one can't help growing older."
"ONE can't, perhaps," said Humpty Dumpty; "but TWO can. With
proper assistance, you might have left off at seven."
