Is 40 years old old

Answer 1

No. Nowhere near it. "Old" is when you can't laugh, think, dance or sing anymore.

40 isn't ancient, although it might seem like it to teens. Most people can still do all the things you want to, physically and emotionally.

Answer 2

No, 40 years old is not considered old. It is still relatively young in the grand scheme of life and many people continue to lead active and fulfilling lives well into their 40s and beyond.
