Anderson called the other guy a “little twerp” which made […]

Antonio Rinaldi points me to this journal article which reports: We found a sinusoidal pattern in CMM [cutaneous malignant melanoma] risk by season of birth (P = 0.006). . . . Adjusted odds ratios for CMM by season of birth were 1.21 [95% confidence interval (CI), 1.05–1.39; P = 0.008] for spring, 1.07 (95% CI, […]

Macartan Humphreys supplied this amusing demo. Just click on the link and try it—it’s fun!
