A while back I was looking into why Puerto Rican men are so effeminate and I stumbled upon this:

9-year-old boy from Aguadilla whose estrogen level exceeds that of an ovulating woman.

These children are part of a public-health disaster that has been called Puerto Rico's Love Canal. The affliction is abnormal sexual development. It is estimated that 3,000 youngsters are affected.

Are you Puerto Ricans wearing thigh highs now? What are the science implications of this?
