2 . One of the first things that Harvard University professor Daniel E.Lieberman points out in his new book Exercised is the double meaning of the word. Not only does it mean voluntary physical activity,but as an adjective,exercised suggests being worried, anxious or tired.And there lies the problem with exercise. Most of us just don't like doing it.
Lieberman pursues a double course in"Exercised: Why Something We Never Evolved to Do ls Healthy and Rewarding'". The professor presents an in-depth look at how humans evolved from hunter-gatherers who didn't have to think twice about getting enough exercise, to those of us who have to push ourselves away from our couches and devices. The parts of the book devoted to biology and evolution can be a bit hard to understand, although Lieberman often introduces them nicely with anecdotes.
Throughout his book, Lieberman discusses the origins of exercise, a modern pursuit.In the 1700s, Samuel Johnson didn't consider the words"play"and"exercise"worthy to be included in his dictionary. Although children have always played and sports have been a "human universal,exercise outside the context of sports was extremely rare until relatively recently, Lieberman writes. He also considers various contemporary forms of exercise and their benefits: running (which he does), walking, dancing, weight training, games and even cage fighting. He drops in on a Swedish company in Stockholm whose CEO requires a weekly "sports hour"to be participated in by all employees.
However, Lieberman's primary viewpoint- that exercise is indeed good for you-comes with an important warning.It must be enjoyable.The paradox（矛盾的情况），he writes，"is that our bodies never evolved to function optimally（最佳地）without lifelong physical activity but our minds never evolved to get us moving unless it is necessary, pleasurable or rewarding.
Exercise,he writes should be social."None of us is an island when it comes to health. Our well-being is interconnected. Some is better than none.Keep it up as you age."
