If there is one thing that the body really hates it is extremes of anything for too long. That doesn’t mean, however, that you should want or expect a life devoid of difficult situations. Unexpected, scary and challenging events are a natural part of living and we deliberately experiment and take risks in the hope of achieving satisfaction. The body has a system to deal with the ups and downs of living, one that enables it to maintain, or return to a healthy balance. The body utilizes pairs of opposites to work together – for example, chemicals, responses, muscles – to enable controlled actions to occur throughout the body.
