Some thoughts about our State of health

Human genetic material is more than 99% identical among the entire human race. You and your parents, siblings, children, cousins, the neighbors, and the people on the other side of the world have the same blueprint of life and identical building blocks. Why is it then that one person has an organ failing while another has a different problem and a third person does not show any health problems at all? How is it that we have identified more diseases in human beings than in any other species in the world? Why is it that the number of cancer cases is growing rapidly among rich countries and not in poor countries with larger populations? If our health problems cannot be explained by genetics, what is their cause? There is a broad consensus among scientists and health professionals over the role of our life styles in determining the general state of health.
