Artificial light makes a difference. Correlation does not imply causation... In this context I've heard discussion of high-fat diet, hormones in meat, ... --------- That was what I have heard as well- that diet has more to do with it. The feeling being that the body "senses" the amount of energy available for things like reproduction. Due to higher caloric intake, the body feels that it is ready to reproduce that much sooner. That would also explain why many women marathon runners experience amenorrhea. The body senses that there are no extra calories to divert to pregnancy and suppresses epithelial build-up, ovulation, etc... warbi
