How many times a day do you check your email When you wake up Before bed A dozen times in between The technology that was supposed to simplify our lives has become the ultimate time-suck: the average teen spends more than seven hours a day using technological devices, plus an additional hour just text-messaging friends.
The advantage to all that gadgetry, of course, is connectedness: email lets us respond on the go, and we are in touch with more people during more hours of the day than at any other time in history. But is it possible we’re more lonely than ever, too That’s what MIT professor Sherry Turkle observes in her new book, Alone Together, a fascinating portrait of our changing relationship with technology, the result of nearly 15 years of study.

help you gain the most ground on someone or something, whether escaping from it
or chasing toward it.”① Thus, when faced with a hostile confrontation
with a person, one will be able to speak, fight, or flee. As martial arts are a
form of training for the fight, parkour is a form of training for the flight.
