Sarcasm. Sarcasm is the lowest form of wit, there is no art to it. Oftentimes it is meant to be funny, it relies on putting another person down and as a result will often make those people look or feel small.
Historically, we had plenty of probiotics in our diet from eating fresh foods from good soil and by fermenting our foods to keep them from spoiling. However, today we use refrigeration and other agricultural techniques to preserve our foods. These newer aged techniques not only do not harvest the growth of healthy bacteria in our bodies but sometimes contact antibiotics that can kill off the good bacteria in our bodies. Thus, we must add probiotic foods into our diet to make up for this.
