Please do help me explain this quotation... im really confuse...thanks?

Question

EXPLAIN: "Youth ages, immaturity is outgrown, ignorance can be educated, and drunkenness sobered, but STUPID lasts forever"

Answer 1

Think about this exchange:

Bessie Braddock: “Sir, you are drunk.”

Churchill: “Madam, you are ugly. But in the morning, I shall be sober.”

Answer 2

It is saying that youth,immaturity, ignorance and drunkenness can be changed but stupid can't.

Answer 3

I think it has something to do with self-awareness. You get older, you get more mature, you get smarter, you can go to rehab, but if you don't realize your faults/shortcommings etc then you can never be wise.

Smart doesn't equate to wise?
