If you've ever groused that you don't get enough sleep, you now know that you're not alone -- far from it, in fact. The Wall Street Journal has provided a rare glimpse at the tracking data from hundreds of thousands of Jawbone Up wearers worldwide, revealing both their collective sleeping habits as well as their activity when they're awake. And... it's not looking good. Even in well-rested cities like Melbourne, the average person slept just over the minimum recommended 7 hours. In Tokyo, many people get less than 6 hours. You don't want to look to your friends for help, then, since they're probably just as groggy as you.
