One 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.

This story is in no way an endorsement of suicide. It's a description of one woman's choice and what came of it.

Five years ago, after doctors told her that she had Alzheimer's disease that would eventually steal her ability to read, write and recognize people, Sandy Bem decided to kill herself.

Sandy was 65 years old, an unsentimental woman and strong willed. For her, a life without books and the ability to recognize the people she loved wasn't a life she wanted.

Patricia East is a developmental psychologist who began her career working at an OB-GYN clinic in California. Thursday mornings at the clinic were reserved for pregnant teens, and when East arrived the waiting room would be packed with them, chair after chair of pregnant adolescents.

It was in this waiting room, East explains, that she discovered her life's work — an accidental discovery that emerged from the small talk that staff at the clinic had with their young clients as they walked them back for checkups.

From the first explosion in Boston on Monday to the second, just 15 seconds elapsed. And in those 15 seconds, three people were mortally wounded, including an 8-year-old boy. The number of injured topped 100, and for those of us watching, it was a profound reminder of a reality we'd prefer to ignore.

All day long we're surrounded by faces. We see them on the subway sitting two by two, pass them on the sidewalk as we make our way to work, then nod to them in the elevator.

But most of those faces don't tell us much about the emotional life of the person behind the face.

Were people happier in the 1950s than they are today? Or were they more frustrated, repressed and sad?

To find out, you'd have to compare the emotions of one generation to another. British anthropologists think they may have found the answer — embedded in literature.

Several years ago, more or less on a lark, a group of researchers from England used a computer program to analyze the emotional content of books from every year of the 20th century — close to a billion words in millions of books.

Ever since she was a small child, Samantha Grimaldo has had to carry her voice with her.

Grimaldo was born with a rare disorder, Perisylvian syndrome, which means that though she's physically capable in many ways, she's never been able to speak. Instead, she's used a device to speak. She types in what she wants to say, and the device says those words out loud. Her mother, Ruane Grimaldo, says that when Samantha was very young, the voice she used came in a heavy gray box.
