ok wonder how much time you took to research all that, now anyways go run a 200 or better a 400 yard sprint and tell me you stil think the same way, you wont, sprinting is safer than jogging, but walking is safer than sprinting which i should of specified, its not bro science its real science which thousands of athletes can contribute too, if jogging is what you want im not going to stop you, but by experience (which obviously you dont have) sprinting along with other anaerobic activities will get you in better shape and a better body with healthier joints than jogging
