What he does seems very staged and dangerous. Swimming under a tangle of driftwood was about the DUMBEST thing I have ever seen. There was about 5 minutes of real content in the total show. So I decided to take is as any other entertainment, with a gain of salt.
I did get on his chat and I think that you could ask a question but they were not answering any of the real people logged on. I looked at the name of the person asking a question and then compared that to the list of logged on people and they did not match. So I think even the questions were very stagged.
What he does could not be filmed without staging it.
