Effects of lack of natural light Many experts say that the lack of natural light may make negative effects on people in the workplace. I completely agree with this statement. Firstly, the lack of natural light may be considered as one of the reason for decrease performances, because workers become tired much quicker by using artificial lighting. Moreover the chance to make mistakes is higher compare with normal conditions. For instance, it is widely known how important the right lighting is for grocery shops, perfume shops and clothes shops. Secondly, the artificial lighting can lead to a deterioration of health by and large and to different problems with eyes in particular. Besides high frequency blinking of the artificial lamps often is a cause for people to have a headache. In conclusion, I would like to say that companies have to pay much attention on the problem of lack of natural lighting in order to decrease the negative effects.

A letter to my friend Dear Sam! How are you doing? Hope you’re well. I’m writing to let you know that everything is all right. Also I’d like to share with you my impressions of “New artist exhibition”, which I visited with my children last weekend. As you know I’m not good at art, but it was really a great experience. Moreover I can say with all honesty it was the most exiting art event I’ve ever been in my life. It was worth seeing. I liked it very much. A lot of wonderful works of art were shown in several sections. We were able to see modern pictures as well as sculptures made in ancient style. In addition, all exhibits were put up for sale. Therefore taking the opportunity I bought a beautiful Chinese vase made in techno style as a gift for my wife. As far as I know given the great success of the event last weekend the management is going to organize the exhibition in a couple of weeks again. I recommend you to visit it. I’m guarantee you will get a lot of enjoy. Your friend, Valera

Fast food pros and cons Finally, I decided to practice my writing on different topics. Fast food is a widespread type of meal nowadays. Millions of people every day buy a huge amount of hamburgers, chips, muffins and so on. However many experts say that it is an unhealthy food and call it as a “junk” food. On the one hand, fast food is tasty, cheap and ubiquitous. Moreover, buying this food people saves much time and efforts because they don’t need to go to the supermarket, cook and do the dishes. That is why fast food is very popular among students and busy working people, who are always in hurry. On the other hand, it is known that much amount of fat is used in production of various types of fast food. Therefore many experts consider this type of food as a cause of overweight. Besides, eating a lot of snacks containing much sugar may lead to serious problems with health, in particular it increase the risk of diabetes. In my opinion having fast food for a lunch is sometimes a good solution for people who are really overwhelmed with a work. In this case it will save time but will not have any effect on the health. Thanks for helping.
