Humans move continuously as part of normal living, even when asleep. The health of your heart, lungs, and digestive system-and even your mental health-are greatly improved through exercise. In modern times, technical aids have significantly reduced opportunities for physical activity; e.g., jobs are more sedentary, household chores require less physical effort, and commuting usually involves sitting in a vehicle. The result is increased obesity and ill health in the population, with the extreme case of type 2 diabetes becoming far too common in youth and younger adults. Individuals, governments, and corporations (particularly in the fitness industries) attempt to counter this through various exercise schemes, and, given the human motivation to win, sports are thought to play a leading role.
