We live in a world full of potentially harmful things. Germs, bacterias, viruses and diseases are just a few of them. Over a period of thousands of years mankind has survived many infections and pandemics, some of which wiped out large portions of people. The black death, the Spanish flu, tuberculosis, and cholera are just a few needles in a haystack of pandemics that mankind has survived over time. Unfortunately, when it comes to these types of things there is no such thing as "risk free." This is just a part of life. The only way for mankind to be at absolutely no risk at all would be for us to live in a completely sterile world, which is inevitably impossible. There are many things in life in which we can never be one hundred percent sure. Our health is one of them. However, there are many things we can do to increase the chances of avoiding certain diseases and viruses and such. Many of these things don't even cross our minds. Some of them are quite simple and even enjoyable. The immune system is designed to fight off disease. Maintaining a healthy immune system is a must. Acheiving accurate sleep is very important in order for our body not to be run down. Nutrition is also key to staying healthy, whether it be eating/drinking too much of what we shouldn't or not eating/drinking enough of what we should. Vitamin C is a well known friend of the immune system. Very commonly, when one becomes ill, orange juice is at the top or near the top of their grocery list. But it's not just orange juice that is high in Vitamin C. Many other fruits and fruit juices also contain this vitamin. These fruits and juices are quite easy to obtain as well. Most of the time they're readily available at the nearest grocery store or market. Many other fruits and vegetables also contain important vitamins that are extremely beneficial for the body. For those that aren't a fan of eating fruits and vegetables, both are available in juice form and in many different combinations. And for those that aren't a fan of either, there are many vitamin and mineral supplements that can be easily taken by mouth. Meat is also high in protein, which is very good for the body. There are also protein supplements for those that don't eat meat. Also, it is very important to keep the body hydrated. This is especially necessary if one is running a fever. Liquids high in antioxidants are especially helpful. But one simple, nearly always readily available liquid, is very important: water. Regular exercise can play a big role in one's health. Whether it be more strenuous exercises such as lifting weights, swimming and things of this nature or simple things such as running, jogging, or even just walking, the benefits are undeniable. These activities can help control high blood pressure as well as help prevent heart disease and maintain a healthy respiratory system. Being overweight can lead to certain diseases. These activities help control weight and boost energy. More energy leads to a better mood. In the world we live in it's virtually impossible to live without doctors. Life is not always fair and no one is exempt from the common cold, the flu, cancer, pandemics, plagues, etc. But the healthier one can be, the better chance the body has to fight off certain viruses and diseases. A combination of sleep, good nutrition, excercise, and numerous other things greatly strengthen our body and help it to maintain good health. When our body feels good, we also feel good, both physically and mentally. The better we treat our bodies, they better our bodies will treat us. Staying healthy is the best way to live a happier, longer life.
