[EX Q]: Article: It's good to make mistakes,and here is why. First of all,mistakes are a clear sign that you are trying new things. It's always good to try new things because when you are trying new things you are growing. If you never try anything new,how can you improve?How can you expand?The simple answer is"You can't."Look around you. With very few exceptions,either every-thing you see in your world or every single detail of every single thing is the result of someone trying something new. Another good thing about mistakes is this:When you are making mistakes,you are learning.Consider this:Edison failed 10,000 times before he perfected the 1ight bulb.When asked how it felt to fail that many times,he said that he hadn't failed 10,000 times,but rather had learned 10,000 things that didn't work. Finally,when you make a mistake you are much closer to success.Why?Because when all is said and done,you will have tried some numbers of things before you succeed.Every time you make a mistake you eliminate one of those things and are one step closer.But this all doesn't mean that you should go ahead without considering the consequences of a mistake.Quite the contrary,when you try something new you have to be willing to set some reasonable limits so that in the event that it doesn't work out the way you want it to,you will he in a position to try again. We all have limited time and money so don't blow them all on one approach to a problem.Realize that it probably won't be perfect the first time and allocate these resources properly so you can learn,make corrections,and try it again.If you accept and use your mistakes in this way,you can make great progress in your business and your career. There is an old saying that goes,"If you're not making mistakes,you're not trying hard enough."So go ahead and make mistakes.And learn.And grow.And succeed.

[EX Q]: Article: Nature is full of color, from rainbows and roses to butterfly wings and peacock tails. Even the fruits and vegetables you eat have different colors: blue blueberries, red strawberries, green broccoli, and orange carrots. Plant and animals often use color to attract attention. The substances responsible for these colors belong to a class of chemical called antioxidants . Plants make antioxidant to protect themselves from the sun's ultraviolet(UV) light. Ultraviolet light causes chemicals called free radicals to form within plant cells. They can destroy parts of plant. Free radicals also have damaging effects on human beings. Some of these effects like wrinkled skin can be seen. The damage is caused by the free radicals attacking cells in our bodies. Certain cancers and heart disease are linked to free radicals. Our bodies have natural defences for fighting off free radicals. While we are young, our defences are pretty strong. However, they get weaker as we get older. The body's built-in defences can only go so far without extra help. The key to fighting free radicals with fruits and vegetables is to mix and match colors. It's like sunscreen for the inside of your body. Go for a range of very bright colors. Colorful foods contain hundreds of healthy chemicals not found anywhere else. Research into how chemicals in blueberries affect the brain's function in rats suggests that these chemicals may help our own brains work more efficiently. Don't just blame the sun. Ultraviolet light isn't the only source of free radicals. If you breathe polluted air such as smog, automobile exhaust , or wasted gas from a factory, you take in chemicals that also cause such damage. And, the body itself produces free radicals as it processes food.
