Why did Wen Jiabao start practicing "Tai Chi"? Did he want to fend himself from any further shoe attacks?

His poor health is apparent, too much boozing and womanizing are bad habits so he practiced Tai Chi for better flexibility, the poor girls at hair salon are doing all the work. The shoe that was thrown was made in China, didn't have much aerodynamics, he was lucky it was just one shoe. I would have thrown my soiled undies on him.
