There is no problem with reply to an old tweet by someone famous.
You say 'I have _ years' So if you were 16 you would say 'J'ai 16 ans'
if you mean reply you would say : Yo tengo # anos.
Cuantos anos tienes?
Mr. Ewell spits in atticus's face and asks if atticus thinks he's to good to reply, this is when atticus says "no, to old."

When you are talking about yourself, you say "Tengo (your age) años."
One where someone asks the questions: - how old are you? -What is my phone number? -How old is my brother.... Or any other personal questions that 99.9% of people don't know......

Someone can recycle old horseshoes by giving them to friends or family. Most people are happy to receive such gifts. Otherwise, one can make a post of Craigslist asking if anyone wants used horseshoes, and he will most likely receive an immediate reply.
If someone asks you how old you are in Italian (Quanti anni hai?), they are literally asking you 'How many years do you have?' In reponse, you would say: 'Io ho [number] anni.' This means, 'I have [number] years.'
The Spanish word for "old" is "viejo".
