Dan Drezner recently attended his 20th high school reunion and offers several interesting observations. Among them:

1) Physically and emotionally, the men will have changed much more than the women. This is mostly physiology — boys mature later, and are the ones who go bald. Plus, if they’re very, very lucky, the men will also meet someone who can dress them better than when they were in high school.

3) That person you had a crush on in tenth grade? They’re still going to look good twenty years later.

6) There will always be at least one woman who has given birth to many children in recent years but look like they could do a guest-hosting stint on E!’s Wild On series.

Having attended my own 10th and 20th reunions, I would offer a corollary to the above: There will be at least one woman who was hot in high school but no longer is but nonetheless thinks she still is. Ditto the reverse–ugly ducklings who emerged as swans but lack awareness of same. Women, much more than men, still define themselves by who they were in high school. Possible exceptions include men who were star athletes or otherwise peaked as teenagers.
