Answer:
Acquired immunodeficiency Syndrome (AIDS) is a syndrome caused by the human immunodeficiency virus (HIV). Up till today, there is not a proper cure for the syndrome but specific drugs can be given to the patient to control or reduce the virus in the patient. Some of the medicines used are:
Lamivudine (Epivir, 3TC), Tenofovir (Viread, TDF), Abacavir (Ziagen, ABC), Indinavir (Crixivan, IDV) etc.
The treatment of AIDS is nowadays far better than the initial years in which AIDS became common. Scientists could not make medicines for reducing the HIV virus and also did not know how this virus spread from one person to another.
In the near future, scientists are working hard to produce vaccines for developing immunity against the virus and also looking for genetic engineering methods to treat AIDS.
Obesity is a physical condition where the BMR (Basal Metabolic Rate) is over 30%. There are few factors that contribute to obesity, such an over average daily calories intake, the lack of physical exercise and in general the lack of healthy habits in the current lifestyle.
In order to reduce obesity, it is necessary to learn what kinds of foods are good for our body and what are not: there are guidelines from different association, such as the American Society for Nutrition, that indicates that is possible to reduce obesity is possible if people are going to start eating healthy and exercise regularly.
Eating healthy means that there should be plenty of vegetables and fruits incorporate into the diet, where other foods such as red and processed meat should be consumed in small quantity or not at all. Drink plenty of water is another suggestion that is possible to give.
As a young person, I think it is time to take responsibility and starting a more healthy lifestyle, in order to live just as our parents if not more. On the other side, there is the fact that eating unhealthy is sometimes cheaper and easier, while perhaps the school system should encourage and teach us that it is possible to feed ourselves in a way that is going to make us live longer and be healthier.
