Mirroring (or subconsciously imitating your conversation partner’s facial expressions, speech patterns, gestures, and even breathing patterns) allows for empathy and stronger connections.

People spend 46.9 percent of their waking hours thinking about something other than what they’re doing, and this mind-wandering typically makes them unhappy. So says a study that used an iPhone Web app to gather 250,000 data points on subjects’ thoughts, feelings, and actions as they went about their lives.

The study, which is published in the September issue of the journal Social Science & Medicine, looked at the reading patterns of 3,635 people who were 50 or older. On average, book readers were found to live for almost two years longer than non-readers. The researchers discovered that up to 12 years on, those who read for more than 3.5 hours a week were 23% less likely to die, while those who read for up to 3.5 hours a week were 17% less likely to die. Overall, during follow-up, 33% of non-book readers died, compared to 27% of book readers.

“By substituting concrete and steel with wood from sustainably managed forests, the building industry could curb up to 31% of global carbon emissions, according to research1 by Chad Oliver, a forest ecologist at Yale University in New Haven, Connecticut. In time, such a shift could help humanity to pull CO2 out of the atmosphere, potentially reversing the course of climate change.”

But only if the wood is harvested from sustainably managed forests.
