.If we could implant a cellular neural-net chip in the human brain, our consciousness could, theoretically, jack in and out of virtual realities, transmit and receive thoughts mind-to-mind, no "virtual reality" mediation necessary.Genetic Engineering is a fact of life today.The goal of the Human Genome Project--slated for completion early in the new millennium--is to map the entire human genetic code.When successfully completed, our knowledge of genetics will increase dramatically and relatively suddenly.We will know exactly what gene and combinations of genes produce which physiological, neurological, and psychological characteristics.Our genetic engineering skills and abilities should increase commensurately.Indeed, genetic engineering may become a branch of another exotechnology.Nanotechnology would enable genetic engineers to manipulate single atoms to create structures (like molecules or genes) that can in turn be used to create even larger structures (like materials or beings).A Virtual Reality version of such genetic nano-engineering is inherent in Doyne Farmer`s and Chris Langton`s field: Artificial Life.You can think of a computer in two ways: You can think of a computer as something that runs a program and calculates a number, or you can think of a computer as a kind of logical universe, a digital universe that you can make behave in many different ways.We believe we can put into computers sufficiently complex universes able to support processes that with respect to that universe, would have to be considered alive.the goal is to abstract what it is to be alive from the material.(Brockman, p.5)Genetic Nano-Engineering is also the great small hope for another exotech: Cryonics is the low temperature preservation--freezing--of people who by today`s standards are dead, with the expectation that improvements in medical, biological, neurological, mechanical, computer technology will allow the reversal of the errant process--the malfunctions--that caused the individual to die.--Ralph Whelan,Editor, Cryonics With nanotechnology Future medicine will one day be able to build cells, tissue, and organs and to repair damaged tissue.This, obviously, would include brain tissue suffering from pre-existing disease and the anticipated effects of freezing.These sorts of advances in technology will enable patients to return to complete health from conditions that have traditionally been regarded as nonliving, and beyond hope, i.e., dead.(Regis, p.4)Fast food chainsFast food is food which is prepared and served quickly at outlets called fast-food restaurants.It is a multi-billion dollar industry which continues to rapidly grow in many countries, as fewer people are eating at home.Ten years ago, they were practically unheard of by most of people.Nowadays their attitude to fast food has been completely changed not only in loads of conutries, but especially in the USA, the source of most of its innovation, where fast food restaurants are extremely popular.Despite the fact that previously it was considered to be very good and trendy, today youths are a lil bit more sceptic and somehow try to reduce the amount of such kind of food eaten every day.So I shall analize this topic carefully within USA.One major advantage (as its name points at) is that is pretty fast.In the USA loads of people do not have enough time to prepare meals and wash up.They are too busy and the only way to satisfy their hunger are fast food chains, where most of meals are self-made which seems to be very important for not only buissnesmen, but also for students.Secondly, its availability is an important issue as well.In the USA, Mc Donald's tend to be located outside the centres of towns.They are usually found on the main roads leading in and out of town.On toll-free highways there are no service areas in the USA so the highway traffic uses the same services such as restaurants and gas stations as the people in each town.Consequently, there is no problem with finding fast food restaurants.However, the cooking method is partly responsible for the food's unhealthyness.Fast food is commonly deep fried, and thereby contains more fat and calories.The cooking oil used to fry the food contains trans fats which are damaging to the heart.As a result, it may lead to many diseases, for instance obesity.That's why loads of people in the USA are getting fatter and fatter.After this, fast food may contain unwanted chemical additives hidden and lack proper labelling, which are damaging to the heart.Eating so many calories is really harmful and unhealthy, it might be dangerous to the human body.Especially one's immune system may not work normally due to of lacks of necessary vitamins.On balance, because of its convenience, fast food is popular in the USA and commercially successful in most modern societies, but it is often criticized for leading to obesity.Fast food portions are usually larger than the amount one should consume in a serving, so in my opinion eating in Mc Donald's should be limited as much as possible.Fast food is not healthy?Do you think that fast food is good for our health? Many people eat fast food and they don't know haw that food affects their health and life.People know too little about the properties and results of eating fast food.We should know something about products that we want to eat.First of all at many fast food restaurants a single meal gives a disproportionate share of recommended daily intake of fat cholesterol salt and sugar.We shouldn't eat fast food because the meals don't contain elements which are needed for life.Furthermore around the world traditional diets and recipes are yielding to sodas, burgers and other highly processed items that are high in fat sugar and salt-fuelling a global epidemic of obesity diabetas and other chronic illnesses.On the other hand if we haven't time so as cook at home we may buy fast food because it's cheap quick and heavily promoted.In conclusion fast food is not healthy but if we eat cautiously between whiles we may be quiet everything will be OK.The little quantums of fast food shouldn't harm us.We should care about our health.As Ralph Waldo Emerson says: "The first wealth is health".Anorexia NervosaAnorexia Nervosa is an illness that mainly affects adolescent girls.The most common features are loss of weight and a change in behavior.The weight loss may become severe and life threatening [ Pobierz całość w formacie PDF ]
