Many of us seek the reassurance of constancy. We enjoy knowing what to expect and seek confirmation that all is well and will continue to be so. Hence the popularity of horoscopes and fortune tellers. Change can seem like a threat.

However, recent events suggest that change is inevitable. Nature is in a constant turmoil, and natural events can bring chaos in their wake. It is worth remembering that change can be positive as well as negative. Some of the most important medical developments, notably the discovery of penicillin, have happened by accident, by someone noticing change and exploring what it means.

May we learn to be resilient and to make the best of the opportunities life offers.
