I'm wondering if there should be an "s" when telling about ages. I have heard from my native English friend says "I'm 24 year old" is it correct?

This question appears to be off-topic. The users who voted to close gave this specific reason:
When describing someone by their age, you would drop the 's'. This is because when you express a unit of measurement (in this case time, or age) as an adjective, it become singular.
However, when someone is stating their age, you would attach an 's'.
I think anyway, hope this helps some. :)
