Our bodies - whether we like them or not - are essential parts of who we are. Looking after ourselves has to include looking after our bodies. We are fortunate in that we know much more about how our bodies work than in previous generations. Modern medicine can appear to work miracles. However, there is much that we can do for ourselves - healthy eating and exercise are an important part of this.

There is another body to be thought about - not just our physical bodies but the body of the world around us. Hence we need to think about how we can care for that body by the ways in which we choose to live. Being 'green' is now mainstream. It is something that we all have to think about.
