Let's say for a minute, that hypothetically, everyone was in fact kung fu fighting. Now statistically speaking of course, this is impossible. Now hypothetically if they were, hypothetically of course. Now, would they all be performing the same so called Kung Fu move? Statistically speaking that is highly unlikely. This would also, hypothetically, be quite dangerous if it were to actually occur. Coming from a medical official, my wife, who is a doctor, she says that hypothetically, this would be dangerous. So, logically, this would not happen. So in fact, there is no way, impossible even, that everybody was Kung Fu Fighting.
