There are a lot of weird health statistic anomalies around the world. For example, the 11% of US adults are smokers compared to 17% in Japan and 25% in Spain. But both Japan and Spain have a lower lung-cancer incidence rate than Americans (Spain is much lower than both!)
Is the rate of cancer actually low or are a lot of cases never formally diagnosed? People in India might not "exercise" much in terms of going to the gym or running but they might still be physically active in other ways.
