Is it too late to start over a new life at the age of 28?

I don't even need to read your paragraph to answer your general question. Of course it's not too late to start over a new life at the age of 28. It's not too late to start over a new life at *any* age. That's a fact! You want to know when it's too late? When they close the lid on the pine box, that's when.
