The new fad in the exercise world -- the Fitbit. It tracks your steps, your sleep habits, the number of flights of stairs you climb, and even your food and water intake. Before you have one, you wonder how people can be so obsessed with a band around their wrist. You’ll probably question their sanity. But once you wear it long enough, you’ll start to fixate on it too.

1. It becomes your favorite accessory.

You can’t risk not wearing your Fitbit with a nice outfit, because the possibilities for steps are endless.

2. It affects your mood.

Under 10,000 steps or eight hours of sleep? Look out, world, there’s a crabby spell coming on.

3. You start to actively compete against your fellow Fitbit friends.

And wonder about those people who average 17K steps a day.

4. You get overly excited when it buzzes alerting you that you’ve reached a goal.

Then you can sleep soundly knowing you’ll get a star on your chart.

5. You can calculate the approximate number of steps it takes to reach a particular place.

An extra walk around the block? Add 750.

6. You take the stairs just to watch your number of flights increase.

And experience guilt when taking the elevator.

7. You’ll do anything to reach the 10,000 mark.

It’s the little things when it comes to the Fitbit. So you take the long way.

8. You find yourself talking to other people about your Fitbit.

“I know it doesn’t work with the outfit, but I’m attached.”

9. You get sad when your Fitbit dies at the most inconvenient of times.

You wore it for a whole day, and it wasn’t counting.

10. You have to wake up in the morning and check on the quality of your sleep.

Only 12 minutes restless!

11. You bond with other people over your Fitbit addiction.

Glad I’m not the only one …
