That's fascinating because it implies that our ability to feel/respond to spicy food is all psychological. I would have figured that you would have felt at least some pain build while eating really spicy food but I guess not.
The response to spicy food is not all psychological. It's due to activation of heat receptors by capsaicin. Note: many factors affect the subjective experience of taste sensation.
I have been put into atrial fibrillation by the aggravation caused by spicy food from a popular indian restaurant in north Seattle. I had to get cardioverted. Was it due to stress? Was it due to the sustained rise in blood pressure? Was it caused by GI? It doesn't matter. I have to avoid it now, for safety.
I, too, have dined at Taste Of India, and paid the price. I'll do it again too!
My mouth can handle the spiciest food one can order. Unfortunately, my GI system isn't quite so tough.
