I'm not one of those guy who desperately want to fool magicians.
The reason I want to fool the doctors is because I work with doctors and paramedics every day and I can tell them that I found a way to stop the blood from flowing to my arm thus creating a natural tourniquet that I can use if I'm injured.
I want to see the look on the doctor's face when he will see that he can't feel my pulse
I wasn't trying to directly say that you specifically
would be the type of Magician just looking to fool other Magicians. I've just seen and read countless threads of other Magicians who's sole purpose while practicing Magic, was to make that one of their main goals as a practicing magician.
Also, if you tried this on the doctors and paramedics that you know and are in contact on a general basis, just might check other ways to find your pulse other than on your wrist. It's quite possibly you might
be able to fool them for a minute or two minute, but then they might think that what you're doing is not safe and damage to your heart. Then proceed to check your pulse either on neck, or use one of those things that clips to your finger (sorry, but I have no idea what they're called) and check your pulse in various other ways.
Although, that is all just speculation on my part and i really haven't the slightest clue as to how they would react. But from my own personal experience, just after using the Johnson Justification method since I noticed there was a medically trained nurse in the audience. She actually pulled me aside after my performance and told me what I was doing was extremely dangerous and I should never attempt the effect again in the future. At least I can say with 100% confidence that it can really fool them bad into thinking what you're doing is real.
If you do decide to try it on a doctor/paramedic it would be great if you could post the reactions you received here on the forums, and let others know what sort of reactions you were able to achieve. Good luck
