Although the literature evidently highlights that it Health and LeisureIn todays world, stress has become an area of keen interest not only to researchers and neuropsychologist, but to society in general. With the increase in dual income families, access to work and family on the same device, and constant updates from ones favorite sports team or social media, it now seems that individuals scarely get a chance to recover from one stressor before the next appears.Research has repeatedly shown that stress can cause physical illness if undetected and unmanaged. Stress in the modern world, it is certainly true that worry and quarrel can cause all kinds of illness, from backache to servere headaches , or even more serious complaints such as high blood pressure.

With the development of science and technology, it might be possible for people to live for one hundred and fifty years in the near future. However, in my opinion, it may not be beneficial for people to do so. Traditional medicine is growing in popularity and many people are now using methods such as acupuncture and herbal remedies to maintain and strengthen their health. Many of those who have experienced traditional medicine believe that it is more effective than modern medicine. I completely agree with this viewpointMost people now use cars as their main form of transport. An increase in this trend during the last century has contributed to major traffic congestion in cities, and to a decline in the quality of our environment. This essay will look at how this is occurring and what can be done to address this problem.The international mass media has for the first time resulted in the majority of people sharing the same experiences. I agree that this is closing the gap between cultures and is bringing many benefits worldwide. In conclusion, I believe that the disadvantages for people living for one hundred and fifty years far outweigh the advantages. Therefore, this development would be a largely negative one for our society. To sum up, modern medicine relies heavily on artificial products that can harm our health, whereas traditional medicine is natural, safe and treats the whole body. Therefore I believe that it is far better in maintaining overall health. To sum up, the growing use of cars is creating an enormous amount of traffic and is damaging to our environment. In order to reduce these problems, citizens could be encouraged to use alternative methods of transport.In conclusion, the international media serves to educate and involve people in cultural and political issues. It also encourages communication between countries and promotes freedom of information. Therefore, I believe that a global culture has many benefits.To conclude, computers are being used in more areas of life such as communication in the workplace and at home. The result is that people are relying more on computers in their daily lives. Despite the disadvantages, it is highly likely that the use of computers will increase due to the various benefits computers have to offer.One solution to combat the negative effects of the Internet on young people is to ensure they are not overusing it. Limits should be placed on the amount of use and other forms of recreational activity should be encouraged. Another strategy would be to ensure young people have Internet-free days and undertake activities that promote social skills, for example, joining youth or sports clubs. In summary, it can be seen that over-exposure to the Internet can be dangerous to young people. Specifically, it could harm the development of social skills at a crucial time in their lives. We should all try to ensure that this does not happen before it becomes a major issue in our society.
