"Barefoot Mike" gets a lot of attention when he shows up at the beginning of a race. He loves to run and has been running since he was a kid. He loves to race, and often competes in 10K races. But that’s not the reason he gets so much attention. People notice him because when he runs, “Barefoot Mike” runs barefoot.

Running barefoot has become a huge trend in the world of running. “I didn't set out to be a trend setter,” laughed

“Barefoot Mike”, otherwise known as Mike Whitaker. “I've always been a runner, but until a few years ago, I always wore shoes. Then one day I was running after a rainstorm. I stepped off into the grass to avoid a puddle(水坑) on the sidewalk, and accidentally stepped into a huge muddy puddle that had been hidden in the grass. I tried to keep running, but the wet and dirty shoe made it really hard. I figured the best solution was to just get rid of the shoes.”

Mike took off his shoes and dropped them into the nearest trash can. “Then I started running. At first I went really slowly because I was watching out for rocks or other things that could hurt my feet, but there really weren't any problems.” He started going faster. “It felt so good!” Mike said. “My knee, which always ached, didn't ache. My foot was able to spread out so I had better balance. And my feet didn't feel all hot and sweaty. It was awesome!”

“There are actually potential health benefits to running barefoot,” said Dr. Nancy Bower, a podiatrist(足科医师).

A recent study agrees. A team of researchers recently videotaped several people running —first wearing shoes and then barefoot. In almost every case, when wearing shoes, the runners tended to land on the heel of their foot, which they call “heel?striking.” Many runners have impact injuries such as knee pain. Heel?striking may be the cause of these injuries or may make an existing injury worse.

When running barefoot, the runners tended to land on the middle part of the foot. The force is spread out throughout the foot. The ankle, shin(胫部), knee and hip don't get the shock of a hard landing with every step.

Here is an astonishing and significant fact:Mental work alone can’t make us tire. It  sounds absurd.But a few years ago, scientists tried to find out how long the human brain could labor without reaching a stage of fatigue(疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all!

If we took a drop of blood from a day laborer, we would find it full of fatigue toxins (霉素) and fatigue products. But if we took blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.

So far as the brain is concerned, it can work as well and swiftly at the end of eight or  even twelve hours of effort as at the beginning. The brain is totally tireless. So what makes us tired?

Some scientists declare that most of our fatigue comes from our mental and emotional (情绪的)attitudes. One of England’s most outstanding scientists, J. A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin. In fact, fatigue of purely physical origin is rare. ”Dr. Brill, a famous American scientist, goes even further, He declares, “One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.”

What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored, anger, anxiety, tenseness, worry, a feeling of not being appreciated— those are the emotions t hat tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.
