How many people do you know over the age of 100 years? Not many, I am sure noT. On Japan's Okinawa Island, there are 457 people that are over 100-years-old! Okinawa is the healthiest place on earth to live on. The average woman lives to 86 and the average man lives to 78. The majority of the people are healthy and happy. These old folks aren't sitting in chairs because they can't walk. One 96-year-old, named Seikichi Uehara, beat a thirty-year old ex-boxer in a martial arts contest. A 105-year-old woman, Nabi Kinjo, hunted a poisonous snake and killed it with just a fly swatter. Are they drinking some type of magic water? They are so healthy because of the food they eat and their attitude towards life. Most of them are just happy with no stress at all. This just proves that happiness is natures best medicine!
