The people that do karate are just as diverse as people in general. Fitness (or the lack there of )seems to be a problem both in the US and western Europe.There are a few things, people can do to remedy this: dont drive your car to work. Jogging, or cycling to work, is one of the best things you can do for your body. Dont drink to much Coke,pepsi etc (is softdrinks the general term here?) The WHO (World Health Organization) has identified that type of drinks as the number one health problem in the western world. Get regular exercise. (thats really not a problem for the members on this forum )
