On a recent Friday night, 30 men and 30 women gathered at a hotel restaurant in Washington, D.C. Their goal was love, or maybe sex, or maybe some combination of the two. They were there for speed dating.

The women sat at separate numbered tables while the men moved down the line, and for two solid hours they did a rotation, making small talk with people they did not know, one after another, in three-minute increments.

I had gone to record the night, which was put on by a company called Professionals in the City, and what struck me was the noise in the room. The sound of words, of people talking over people talking over people talking. It was a roar.

What were these people saying?

And what can we learn from what they are saying?

The March issue of the medical journal Pediatrics features an editorial looking at gender identity disorder in children. Pediatricians apparently are seeing more young patients who express an interest in changing their gender.

In 2004, after an extensive review, the Food and Drug Administration issued a strong warning to doctors who prescribed antidepressants to teens and children.

Antidepressants, the FDA said, appeared to increase suicide among kids and teens. Doctors needed to be careful. The FDA even mandated that a "black-box warning," the strongest type, be placed on antidepressant packaging.

This warning and worries that giving antidepressants to children might cause them to kill themselves was front-page news for weeks and appeared to changed the prescribing behavior of doctors.

When I was 17 years old, I got so depressed that what felt like an enormous black hole appeared in my chest. Everywhere I went, the black hole went, too.

So to address the black-hole issue, my parents took me to a psychiatrist at Johns Hopkins Hospital. She did an evaluation and then told me this story:

"The problem with you," she explained, "is that you have a chemical imbalance. It's biological, just like diabetes, but it's in your brain. This chemical in your brain called serotonin is too, too low. There's not enough of it, and that's what's causing the chemical imbalance. We need to give you medication to correct that."

Then she handed my mother a prescription for Prozac.
