Bytes of Life

It's similar to a fashionable new trend called lifeblogging, an art form/obsession wherein bloggers go to extreme means to record infinitesimal events throughout the course of a day. Microsoft engineer Gordon Bell famously (at least in very small circles) wears a SenseCam around his neck, which automatically snaps a photograph every 60 seconds of wherever Bell happens to be and whatever he happens to be doing.

But lifeblogging seems mostly like a byproduct of an always-on society. If you do something but fail to record it online, did it really happen?

Self-tracking, on the other hand, is partly about the recording, but also as much about the analysis that goes on after the recording.

The apparent meaninglessness of data recorded over time is actually what makes it profound.

The problem with diaries and blogs, trackers say, is that people use them to record the events they think are meaningful. What they forget is that meaningful events are often a result of months of insignificance, a cause and effect not readily visible to the human eye but easily detected with the help of a computer program.

"Things that happen over time can lead up to bigger events," says Horn. "They may seem small by themselves, but looking at them as a whole I can see how they lead to a bigger theme or idea."

"I was always a terrible self-journaler," says Messina. "Every once in a while I'd write in a journal, but it was always a major, momentous event. 'Got to college.' 'Broke up with girlfriend.' You lose a lot of the nuance that caused that situation to come about."

Tracking can "zoom out over my entire life," he says. It could, for example, help him better understand the aforementioned breakup. "When you've self-documented the course of an entire relationship, trivia that doesn't seem like much could, over time," help him understand exactly what went wrong, and when.

Maybe, to extrapolate on Messina's idea, your weekly date night had been Friday. And maybe you were always in a tetchy mood on Fridays because you'd just come from chem lab, which you hated. Maybe the whole relationship could have been saved by switching date night to Sunday, after your endorphin-boosting yoga class. Maybe you just didn't realize the pattern, because you weren't tracking it. All the answers could be right there, in your life data.

When talking about tracking, Messina speaks thoughtfully and precisely, choosing words carefully and revising his ideas when his original sentence doesn't seem clear enough.

He met Evans when he participated in a research study she was conducting as part of her course work. She was immediately drawn to the insight he showed into his own behavior.

But insight doesn't necessarily translate to emotional intelligence, and people who graph their lives online don't put much weight in intuition and fuzzy feelings.
