I sleep in late whenever I can, and have felt vaguely guilty about it because everything I've read about sleep says people are supposed to stick to a strict sleep schedule every day. That's not possible for me, because I often get up very early to catch a morning flight. Sleeping in on the weekends always feels great. Well, it turns out I should keeping following my instincts.

Researchers at Stockholm University discovered that adults who logged up to five hours of sleep every night increased their risk of mortality. However, when people who only slept five hours a night during the week compensated by snoozing nine hours a night on the weekends, their risk of death did not increase.
To conduct the study — which was published in the Journal of Sleep Research —scientists looked at data on sleep habits collected from more than 43,000 people under 65 years old. Then, they studied death records taken 13 years after the initial data was obtained to determine if and how sleep habits impacted mortality. Of course, other factors like education, body mass index, and smoking can take years off your life, so they accounted for those, too. Their conclusion? "Long weekend sleep may compensate for short weekday sleep."

We love our smartphones and tablets, but we also love to write. For a while now, there hasn’t been a workable solution. Either hook it up to a keyboard (which defeats the purpose of a portable gadget) or resign ourselves to typing on tiny, unresponsive glass icons. Looks like technology has finally caught up to […]
