                    | Our fast paced, technologically based society has
                      had a great impact on human health. Even though our
                      knowledge of what is good and bad for our bodies and our
                      health in general has increased immensely over the last 50
                      years, that has not translated into a healthier population
                      overall. Per capita there are more overweight people
                      living in North America than any other continent in the
                      world. The sedentary lifestyle we have adopted combined
                      with unhealthy eating habits also impacts our body systems
                      which must cope with the neglect and abuse they receive. On the other hand, knowledge of the
                      physiology of our body systems has improved greatly and we
                      have learned a great deal about how we can improve the
                      functioning of our body systems through physical training
                      and proper diet. |  | Diet & Exercise  MenuUp
