Ok, I’m sure there are other factors, but I found this recent poll released by The Harvard Crimson interesting. Among the findings was that 72 percent of those at Harvard enroll as virgins. For comparison, a 2007 study reported that 52 percent of high schoolers are virgins, slightly down from 54 percent in 2002.
Finally, this is just a reason to post this clip from Seinfeld to help explain why these kids might be smart enough to get into Harvard.
