On May 23,1989, Stefania Follini came out from a cave at Carlsbad, New Mexico. She hadn’t seen the sun for eighteen and a half weeks. Stefania was in a research program, and the scientists in the program were studying body rhythms (节奏)。In this experiment Stefania had spent 130 days in a cave, 30 feet in depth.

During her time in the cave, Stefania had been completely alone except for two white mice. Her living place had been very comfortable, but there had been nothing to fell her the time. She’d had no clock or watches, no television or radio. There had been no natural light and the temperature had always been kept at 21℃.

The results were very interesting. Stefania had been in the cave for over four months, but she thought she had been there for only two. Her body clock had changed. She hadn't kept to a 24-hour day. She had stayed awake for 20-25 hours and then had slept for 10 hours. She had eaten fewer meals and had lost 17lbs in weight as a result! She had also become rather depressed (抑郁).

How had she spent her time in the cave? As part of the experiment she'd done some physical and mental tests. She'd recorded her daily activities and the results of the tests on a computer. This computer had been specially programmed for the project. Whenever she was free, she'd played cards, read books and listened to music. She'd also learned French from tapes.

The experiment showed that our body clocks are affected by light and temperature, For example, the pattern of day and night makes us wake up and go to sleep. However, People are affected in different ways. Some people wake up naturally at 5:00 am, but others don't start to wake up till 9:00 or 10;00 am. This affects the whole daily rhythm. As a result, the early risers are at their best in the late morning. The late risers, on the other hand, are tired during the day and only come to life in the afternoon or evening!

It was a cold winter day. A woman drove up to the Rainbow Bridge tollbooth (收费站). “I’m paying for myself, and for the six cars behind me,” she said with a smile, handing over seven tickets. One after another, the next six drivers arriving at the tollbooth were informed, “Some lady up ahead already paid your fare.”

It turned out that the woman, Natalie Smith, had read something on a friend’s refrigerator: “Practice random kindness and senseless acts of beauty.” The phrase impressed her so much that she copied it down.

Judy Foreman spotted the same phrase on a warehouse wall far away from home. When it stayed on her mind for days, she gave up and drove all the way back to copy it down. “I thought it was beautiful,” she said, explaining why she’d taken to writing it at the bottom of all her letters, “like a message from above.” Her husband, Frank, liked the phrase so much that he put it up on the classroom wall for his students, one of whom was the daughter of Alice Johnson, a local news reporter. Alice put it in the newspaper, admitting that though she liked it, she didn’t know where it came from or what it really meant.

Two days later, Alice got a call from Anne Herbert, a woman living in Marin. It was in a restaurant that Anne wrote the phrase down on a piece of paper, after turning it around in her mind for days.

“Here’s the idea,” Anne says. “Anything you think there should be more of, do it randomly.” Her fantasies include painting the classrooms of shabby schools, leaving hot meals on kitchen tables in the poor part of town, and giving money secretly to a proud old lady. Anne says, “Kindness can build on itself as much as violence can.”

The acts of random kindness spread. If you were one of those drivers who found your fare paid, who knows what you might have been inspired to do for someone else later. Like all great events, kindness begins slowly, with every single act. Let it be yours!
