The Short Answer

Hate to say it, but you are suffering from confirmation bias. You probably see a high schooler with a beard and *assume* he is older because he has that beard. You do this subconsciously. When you view the yearbook picture, you are contextualizing things differently. Really, the answer is what you already heard. Your perceptions changed. What identifies a person as being more grown than another changes year to year, especially with styles. Beards are now something older people have, so younger people don't have them. Nobody wants to look like their parents.
