They mention that people in the Southern Hemisphere get more sun and have a lower incidence of cancer, but is that also true of Australians? Cause on average, people from the Southern Hemisphere have a lower caloric intake, which has also been linked to lower rates of cancer in general.

That being said, I really enjoy the fact that scientists are following so many rabbits in the war against cancer. This is going to pay huge dividends on the long run.
