Human genomes are building blocks of a human body, so understanding our genetics means better understanding ourselves. Genetics can explain why we have our unique traits, why we have similarities between family members, and how our genes relate to our health (Genetic Alliance 1). One should learn about his or her genetics not only because of curiosity, but because the results of genetic examinations are of great practical importance for medicine and health.

Understanding why certain people have inclinations toward a particular set of illnesses comes from learning about the human genome. Some gene variants can protect from diseases, and some, particularly mutating genes, can cause harm (Lewis 3). As everyone inherits their genes from their parents, it is logical to conclude that there is a possibility one might receive illnesses by genetic means. Learning genetic history may contribute to making healthy decisions and preventing diseases in their early stages of development.

Heart disease, stroke, and cancers are the top three causes of death in high-income countries, and lower respiratory infections, HIV/AIDS, and diarrheal diseases are the primary causes of death in low-income states (Lewis 70). The interesting point is that genes influence all these diseases. Mainly cancer is the direct result of gene transformations in the human body (Lewis 79). Information obtained from genetic tests may not only help prevent illnesses that are common in the family line but also cure life-threatening diseases before they are too mature.

Genetic testing, which is essentially genome sequencing, may not yet be widespread and affordable in contemporary society. As such examinations become a part of standard procedures when diagnosing illnesses with unknown symptoms, the majority of people will have an opportunity to learn about their heredity (Lewis 121). Every individual, however, should consider genome sequencing if possible. The results may greatly contribute to health, behavior, and everyday life.
