Many people somehow believe that it's appropriate to attempt to eliminate many kinds of risks completely. But many tiny risks are more costly to eliminate than to accept. Sometimes the costs are more than money. Human socialization is among the most important and healthy aspects of human life. But some people would completely avoid socializing, or would cover them their faces with masks, to reduce risk, and in the process, live less fulfilling lives. From another perspective, consider what would happen if modern Farms quit using chemicals. We would face slightly lower risks of consequences associated with those chemicals, but we would face massively higher risks associated with crop losses and poor crop quality.
