Many people nowadays have preventative health checks. Increasingly, we screen whole cohorts for disease that, if treated early, reduces the overall impact – breast and bowel cancer being the most well-known. This not only improves the chance of making a full recovery, but also requires less visits to the doctors. Our nations also invest heavily in healthcare for the unwell, but increasingly invest in public health to prevent us getting unwell - the COVID test and vaccination programme being a leading example. So, should we also be making regular health checks on our business?
