Recently my husband had his Achilles tendon（跟腱） cut when feeding a chicken. When sitting in the doctor’s office waiting for surgery stressfully, I decided to treat myself for a minute and start to read about “The Little House on the Prairie”. Suddenly I felt my life seemed like a slack（懈怠） compared to the Ingalls who do all their washing and cooking but they feel so happy. Their every happiness is created from the work with their own hands. Yet I’m walking around feeling sorry for myself because I’m picking up the slack! So I’m thinking “Work it out! Get up and get busy.”

It really is true. I realize that I’m happiest when accomplishing tangible(有形的) productive work—working in the yard and washing my dishes—brings me happiness. This does not surprise Kelly Lambert Ph.D. She has been researching the phenomenon she calls “effort-rewards”. When you do meaningful work with your hands, a kind of neurochemical feedback floods your brain with dopamine and serotonin. These happy brain chemicals are natural antidepressants, and we’ve evolved to release them both to reward ourselves for working with our hands and to motivate ourselves to do it some more. Dr. Lambert says Americans have become more depressed in recent years and at the same time we’ve experienced a decrease in purposeful physical activity. Did we lose something vital to our mental health when we started pushing buttons instead of ploughing the fields?

Dr. Pansinski says she gets that happy look when she prepares a meal at the end of a day. “We are programmed to reward ourselves when we accomplish things with our hands. For so many people, it just feels as though everything’s going so fast—life, kids, hundreds of e-mails a day. There is so little you can really see and hold on to. Working with one’s hands is a way to slow down, to take pleasure in life again.”
