This Chinese man has a particularly electrifying way of keeping his body fit: he let electric current pass through his body!
Zhang, who controls the voltage, once cooked a fish which he held in his hand as the current flowed through his body. He has used electrical current to treat people suffering from rheumatism, arthritis and kidney pain.
Zheng was examined at Xinjiang Branch of the Chinese Academy of Sciences in 1994 and experts said that he has a physical dysfunction, but did not give details.
I wonder what that "physical dysfunction" is ... Link
They filmed the guy while he was healing someone with some infrared camera and the heat was really showing up in his hands.
Maybe this could explain the “physical dysfunction†they're speaking about.
