Possibly. I don't yet follow what relationship this fact has to finding evidence of lower cancer rates. Is it maybe you were answering to some other reply?
Well, people in this thread are saying the people in cold countries should have a lower cancer rate. My point is that people in cold countries may keep their homes warmer, and they might not spend much time below 22C, whereas people in more temperate climates may spend more time below 22C even if the climate is warmer.
