Time travel works like this. You can go from one part of time to another your body and mental state stay the same but let us say in this case I was born in X377 and I stayed in that time for 14 years I would be 14 but then I went through time let us say 400 years Physically and mentally I would still be 14 but in all reality I would be 414 years old. So they may look young but the could be 425-426 years old
