Mexican here. I find it amusing that people focus on how spicy their peppers are. They are missing the point. There are many pepper varieties and each has a different flavor. That is the interesting part and how it mixes with different foods in a variety of recipes. Focus on the flavor, not the burn.
The burn is an important part of the pepper experience. For some, building a tolerance to capsaicin is a hobby. They're not missing the point, they're just eating them for a different reason. And what's nice about building up an extreme tolerance to capsaicin is that afterwards you are able to better experience the flavor of peppers, without focusing entirely on the heat.
For anyone picking up the hobby, know this, you will reach the point where your stomach and other parts of your body will become a limiting factor so build up slowly. I own a bidet.
