We live in a very competitive world. Everybody seems to be competing with someone at some level. Each week we spend hours playing or watching others compete in sporting activities all over the world. We cannot help being impressed by the level of excellence that these people achieve.
In sport and business, competition encourages excellence in performance. Where there is no competition, improvement in performance is less likely. Some level of competition is a have-to in all aspects of life.
The following story makes this point.
As two friends are hiking in the forest they come across a huge, ferocious and obviously hungry bear. Its next meal has just come into sight, and they are it! The first friend calculates that the bear will catch them in 27.3 seconds. At that point, she panics, realizing there is no escape. She faces her friend, with the fear of death in her eyes. To her amazement, she observes that her friend is not scared at all. On the contrary, her friend is quickly but calmly taking off her hiking boots and putting on running shoes. “What do you think you’re doing?” the first hiker says to her companion. “You’ll never be able to run faster than that bear”. “That’s true,” says the companion, “but all I have to do is escape, faster than you.”
We all compete when the motivation is strong enough. However, competition is not the real purpose of life. Fulfilling the measure of our creation can only be achieved individually.
Most of time, we are not in competition with any other person, so we do not have to compare ourselves with others. There is only one person that can fulfill our role and that is us. This means that others cannot beat us to the finish line because there is no race. This is not to say that others do not have a similar role to us, but it is never the same. This is important to understand if we are going to enjoy life. Every human being is unique and cannot be cloned. In this, I am not referring to the body, only to the spirit, soul, or the essence of a person.

Now, we know that if we do not get enough vitamins, we are at risk of developing a number of diseases. As a result, vitamin supplements（补品），though expensive, are popular with people who worry that they are not getting enough vitamins from the foods they eat. But contrary to what many people think, medical experts have found little evidence that most supplements do anything to improve health or protect against disease.
In fact, medical experts warn that taking too many of some vitamins can be harmful. For example, too much vitamin E can cause bleeding. People should discuss what vitamins they take with their doctors, as some vitamins can produce harmful side effects when mixed with medicines.
Experts, however, do say that sometimes vitamins can help prevent disease. People who know they lack a particular vitamin should take vitamin supplements. Some older adults, for example, may not have enough vitamin B-twelve. This is because, as people get older, their body loses its ability to take it from foods. Also, people who spend much time inside may need some extra vitamin D as the skin makes this vitamin from sunlight.
Different vitamins are found in different foods. Vitamin A is found in fish liver oil. It also is in the yellow part of eggs. Sweet potatoes, carrots and other darkly colored fruits and vegetables contain substances that the body can change into vitamin A. Vitamin B-twelve is found in green leafy vegetables and other foods, like fruits. Vitamin K can be found in pork products.
In fact, for most people, a balanced diet can ensure enough of the vitamins our bodies need. So, it is important for us to eat a mixture of foods every day to ensure that we get enough vitamins our bodies need.

A chocolate printer that allows sweet lovers to create 3D desserts by themselves is to go on sale at a cost of 2,500 pounds.
The machine squirts (喷射) out chocolate and, via computer instructions, allows the user to build any shape they like out of the food. But makers Choc Edge have missed the Easter rush. Even so, they hope the printer will be snapped up by retailers (零售商) immediately they come to the market. Britain’s biggest chocolatiers Thornton’s have already said they are interested. Because of the high cost, however, few individuals are likely to buy one. But the devicecould one day allow people to design their own 3D objects after submitting their designs on a website. Dr Hao, founder of Choc Edge came up with a prototype (原型) last year and has only just perfected it so that it can now go on sale. “We’ve improved and simplified the machine, so now it is really easy to use,” he told the BBC. “You just need to melt some chocolate, fill a syringe (注射器) that is stored in the printer, and get creative printing of your chocolate.”
3D printing is a technology where a three dimensional object is created by building up successive layers of material. The technology is already used in industry to produce plastic and metal products, but this is the first time the principles have been applied to chocolate. The research has presented many challenges. Chocolate is not an easy material to work with because it requires accurate heating and cooling cycles. Dr Hao said, “What makes this technology special is that users will be able to design and make their own products. From reproducing the shape of a child’s favourite toy to a friend’s face, the possibilities are endless. It could be developed to help consumers design many products from different materials, but we’ve started with chocolate as it is easily available, low cost and harmless.” “There is also no wastage as any spoilage (损坏物) can be eaten.” Dr Hao added, “Eventually we may see many mass-produced products replaced by unique designs created by the customer.”[来源:]
EPSRC chief executive Professor Dave Delpy said, “This is a good example of how creative research can be applied to create new manufacturing and retail ideas. By combining developments in engineering with the commercial potential of the digital economy，We can see the new market prospect (前景)—creating new jobs and, in this case, the chocolate printer is called sweet business opportunities.”
