[General] Age

[a.lilla]

Hi, I am writing a research project and I'm having a difficulty with something.
I would like to write this: The person in the question is either younger or older than the subject or he/she is.......
And I don't know how I should express correctly that in the third case the person is as old as the subject.
Is "he/she is of the same age as the subject" correct?
Besides, can I use either/or when I want to list three things or is it incorrect?
Thank you!

Is there some 4th alternative to being either:

1. younger
2. older
3. same age?

"The person in question is younger, older or the same age as the subject."

However, as Soothing Dave said, there are no other possibilities, so the "person in question" could be any of the 7 billion people on the planet!

Did you perhaps not want to put all of that in one sentence?

The person in question is younger or older than the subject [but not the same age].
The person in question is the same age as the subject.
