I always think that a mouth and a stomach are a pair of natural enemies. Strong flavor foods usually give us a wonderful feeling which helps our body relases a lot of dopamine. However, everything deosn't go well like wo think. When the food comes into our stomach, our body will give a quite other reflection. Some parts of the food are not necessary for our body, and they are hard to digest. In that case, a pain will sprend from our stomach to other parts of our body. If you are lucky enough, a few tablets can reduce the pain. Otherwise, you need to go to a doctor. I have a very rude saying that goes: when a mouth enjoys his life with whatever he likes, an anusis waiting to bear all the bad consequences. This reminds me of a famous Japanese food called Sushi. It's very plain,but healthy. However, most people around me don't often eat it due to its plain flavor. We really like eating hot pot. A varitey of flavors about hot pot never let our mouth feel disappointed, but always let our bottom hurt.
