We're all "long term studies." Where's the brain-cancer epidemic? People who smoke are more likely to get lung cancer, an otherwise rare disease. So if everybody started smoking, we'd see a large spike in lung-cancer cases. However, we have not seen a large spike in brain-cancer cases across all populations who started using cell phones en masse in the 1990s. So exactly what problem is being addressed here, besides poor high-school physics education?
