Sports is not only physically challenging, but it can also mentally challenging. Criticism(批评)from coaches(trainers), parents, and other teammates, as well as pressure to win can create too much anxiety or stress for young athletes. Stress can be physical, emotional, or psychological, and research has showed that it can lead to burnout. Burnout has been described as dropping or quitting of an activity that was at one time enjoyable.

The early years of development are critical years for learning about oneself. The sport setting is one where valuable experiences can take place. Young athletes can, for example, learn how to cooperate with others, make friends, and gain other social skills that will be used throughout their lives. Coaches and parents should be aware(realize), at all times, that their feedback(反馈)to youngsters can greatly affect their children. Youngsters many take their parents’ and coaches’ criticisms to heart and find a flaw(缺陷) in themselves.

Coaches and parents should also be cautious(careful) that youth sport participation does not become work for children. The outcome of the game should not be more important than the process of learning the sport and other life lessons. In today’s youth sport setting, young athletes may be worrying more about who will win instead of enjoying themselves and the sport. Following a game, many parents and coaches focus on(pay more attention to) the outcome and find fault with youngsters’ performances. Positive reinforcement should be provided in spite of the outcome. Research shows that positive reinforcement motivates and has a greater effect on learning than criticism. Again, criticism can create high levels of stress(pressure), which can lead to burnout.

Whatever our differences as human beings are, we all think we’re more like the rest of the animal world than we realize. It is said that we share 40 per cent of our genetic(遗传的)structure with the simple worm.

But that fact has helped Sir John Sulston win the 2002 Nobel Prize for Medicine. Sir John is the founder of the Sanger Institute in Cambridge, which was set up in 1992 to get further understanding of the human genome(染色体组).

To help them do this, they turned to the worm. The nematode(线虫类的)worm is one of the earliest creatures on planet earth. It is less than one millimeter long, completely transparent and spends its entire life digging holes through sand. But it still has lots to say about human life, and what can be done to make it better.

What the worm told Sir John and his colleagues was that each of cells in the human body is programmed like a computer. They grow, develop and die according to a set of instructions that are coded in our genetic make-up.

Many of the diseases that humans suffer from happen when these instructions go wrong or are not obeyed. When the cell refuses to die but carries on growing instead, this leads to cancer. Heart attacks and diseases like AIDS cause more cell deaths than normal, increasing the damage they do to the body. Sir John was the first scientist to prove the existence of programmed cell death.
