[Q]: Article: It's hard to avoid looking like a fool on April Fool's Day. On April 1 each year, people play tricks on each other. These tricks are usually silly rather than mean. Classmates sometimes tie each other's shoelaces to their chairs.Teachers might hand out an impossibly difficult surprise test that scares students before they realize it's only a joke. Newspapers announce fake contests (such as "Win an elephant!") and report on fake stories (like "UFO" lands in New York City). Forget gifts, songs and special foods--those are for the other holidays of the year. On April Fool's Day, the only tradition is to laugh (and maybe to cause a little bit of trouble). One April Fool's Day, when I was in high school, a group of students in my class played a very clever and funny trick on the teachers. They bought some chickens and set them free in our school cafeteria. The chickens ran all round the school, in and out of classrooms and under our feet. Feathers were flying everywhere. Teachers began running after the chickens, trying to catch them. Finally, they caught four of them. But the chickens were wearing numbered tags around their necks, and the teachers discovered that they had only caught chickens No.1, 2, 3, and 5.Where was chicken No.4? The teachers looked and looked. They couldn't find another chicken. After a few hours, they realized that the students had played another joke on them: There were only four chickens in the first place! They've been tricked by the numbers on the chickens. It's been a long time since I was in high school, but that April Fool's Day remains one of my favorite memories from those years.

[A]: Why did students set chickens free?

[Q]: Article: Research shows that much of our predisposition towards determination, sociability and self - control and sense of purpose is in our genes.In fact, our DNA plays a bigger role in influencing these traits ( characteristics)than our upbringing and the company we keep.Taken together, these aspects of personality can make the difference between success and failure, say the Edinburgh University researchers. They questioned more than 800 pairs of twins about their attitudes to life to tease apart the influences of nature and nurture.Comparing identical twins, who share all their DNA and their up bringing, with non-identical twins, who have a shared background but are no more genetically alike than other brothers and sisters, is a technique often used by researchers to quantify the influence of genetics. The results, published in the Journal of Personality, showed that genes play a much bigger role than lifestyle, with self-control particularly etched into our DNA. Our genes a222so largely determine how determined and persistent we are.This is important in terms of success, as someone who refuses to give up is more likely to achieve their dreams than someone who _ Researcher Professor Timothy Bates said, "Ever since the ancient Greeks, people Lave de hated the nature of a good life and the nature of a virtuous life.Why do some people seem to manage their lives, have good relationships and cooperate to achieve their goals while others do not? Previously, the role of family and the environment around the home often controlled people' s ideas about what affected psychological well-being.However, this work emphasizes a much more powerful influence from genetics." However, those who haven' t been dealt a helpful hand of genes shouldn' t he too depressed.The professor says a sense of purpose is the key and advises those who are eager for success to focus their thoughts on making a difference.
Answer: Our DNA plays a decisive role, in achieving success.

[Q]: Article: Spring is here and so is the cycling season. Here are some tips on how to do it safely and comfortably. Watch your feet--Pushing with the wrong part of the foot can raise your risk of developing a painful injury of the heel and arch , says Rob Werstine, a sports physiotherapist and board member of the Canadian Physiotherapy Association. You should push with the ball of your foot, he says. Layer up--While it's still cool, wear layers of clothing, with clothing close to the body that breathes and outer layers that do not absorb water. Go for bright colors that increase your visibility . Be reasonable--If you are just starting out and aren't in good shape, don't sign up for a 50-kilometre ride. And while cycling is great exercise for people who want to get into shape, if your doctor advises you not to do tiring exercise, cycling shouldn't be your starting position, Werstine says. Walk to begin getting into shape and then graduate to cycling. Fix the fit--If you develop lower back pain or numbness in your hands and fingers from cycling, it could be your bike isn't adjusted properly for your height. A good cycle shop can help you find the right height for the seat and handlebars, but if you have continuing problems, consider consulting a bike fit physiotherapist, Werstine says. Be mindful--You have to pay attention on the roads to vehicles, other cyclists and pedestrians .Consider taking a cycling safety course to practise your skills.
