AKA Monet that was so interesting. You know your stuff!
I think that the overexposure to nonnatural things like air pollution, etc also contribute to reproductive issues in women and men alike. One of my friends was telling me that her mother (who's in her late 50s and lives in another country) didn't start her period until she was 17. Yeah. When I was in 3rd and 4th grade there were already a considerable number of girls with obvious development. I wasn't allowed to drink lots of sodas or eat fast food and I think that's why I didn't start 'til I was nearly 13. Just some thoughts!
