We all have a genuine DNA combination that is made up of our mother and father. Some of us have natural looks that are favorable to our mother, likewise, some of us favor our father. But these favorable looks are due to our DNA combo. We also have strengths that come from a combination of mom and dad. If your dad was a natural fast runner at one point then you have the chance to get that gene in your DNA and be naturally fast. It is highly unfortunate, however, that while we do gain these natural strengths from our mother and father, we also develop a part of us that is weak. There is a natural weakness as in physical strength or being prone to health problems. Ultimately, we will die from one of our weaknesses.
