Pohnpei makes a great point in the previous post. Although many of today's young people (and old as well) are practically addicted to their iPods and laptops, foresaking good old-fashioned exercise for constant texting and video games, modern technology can also provide great ways to stay fit. I was a witness to one of the great advances in physical fitness inventions in the early 1970s: the Nautilus weight machines. The inventor, Arthur Jones, lived nearby (I went to school with his children), and his new ways of exercising and lifting weights were quite revolutionary at the time. I still have a picture of a young Arnold Schwarzenegger using the machines at my high school gym; he traveled across the country just to give the new machines a try. Since that time, Nautilus machines have long since been replaced by newer, more technologically advanced equipment, and the future will only bring newer and better advancements.
