His spelling isn't always the best, so you can tell he's a different nationality (not that all North Americans know how to spell mind you)....but I'm guessing Jewish otherwise he wouldn't even say Shalom. He said he's a pharmacist and his brother is a doctor who works at the hospital where they are doing the studies. He initially didn't even believe in the company and said it will go bankrupt and told everybody to sell, but soon after became a believer and told everybody that this is a winner. I personally trust what he says.
