age

“How old are you?” All of us have wondered about the age of someone we’ve met, but asking this question can be awkward, even during a one-to-one conversation. Making public the ages of hundreds of people in a meeting room — well, that’s even more awkward! Body voting (aka human spectrograms) can uncover this information in a few minutes, but because age can be a sensitive subject, I’ve always demurred requests to have participants line up by age at a meeting.

Until last week.
