This has been a very contentious subject that I've discussed numerous times with friends and co-workers. It revolves around the theory that once the heat level of a pepper reaches the maximum limit of someone's pain threshold then they are no longer able to detect additional heat beyond that level. For example, if a cayenne pepper is hot enough to make someone throw up and go running for the sink, then that same person could eat a trinidad scorpion and have the same ill effects but not realize that it's that much hotter pepper, since their sensory capacity has already been exceeded by a cayenne. On the other hand, some might argue that same person would eat the scorpion and end up in the hospital. I'm just wondering where everyone weighs in on this notion?
