It takes this active walker over a minute to take ten paces, and he is planning to add fifty more kilos to his already unbelievable heavy shoes. So, what’s his secret? Well, he says it all comes down to Qigong-- which is an ancient Chinese practice of controlling the flow of bodily energy. He says the benefit behind such exercise is a cure for back pain.
