Aside from this Globe article being really well written, I think it looks at some interesting parts of our society. The fact is, as human beings, we're wired to look at other people and make decisions - some of them related to sex and attractiveness. We can't (and shouldn't) suppress what makes us human but we should be a respectful part of our society.
I do wish that the author had spoken with some younger people to get their perspective. Maybe it's just me, but I've seen some pretty rude and creepy behaviour from younger men. Although leering and comments have always been around, I've noticed some guys taking "checking a girl out" to a new creeper level. Not cool.
