Canadian researchers tracked 160 wellness indicators to map differences in health between the northern and southern parts of British Columbia. They uncovered stark regional differences -- residents in the southern parts of the province, in some cases, have life expectancies several years longer than those in the northern parts. "The healthiest regions in the province really are in the Lower Mainland and Victoria. ... The wealthier you are, usually the healthier you are," said Aleck Ostry, a University of Victoria geography professor.
