With people in the past living a much more seasonal life, ones in which a diversity of nutrition can only be provided for babies at different times of the year, there is a scientific basis that has been explored. Along with food, babies of the past may have been granted more or less contact with parents depending on seasonal work loads and so on.

Interesting stuff to think about. Seems to be what this article is getting at. Imagine how magnified it was when agriculture played a bigger role.

I am a scientist and I don't believe in Astrology, and I was always suggesting this interpretation to my friends who believe in it. Generally, the answer was "yeah, okay, maybe, I don't really care where it comes from, as long as it's correlated with the stars". However, they always reject the further conclusion that in modern times all these effects must have virtually disappeared. Also, they always confuse statistical correlation with individual people. If someone is 55% likely to have some trait, while other people are 50% likely to have that trait, it doesn't really mean you can make a definitive conclusion about a single person you see. It will only apply if you see 1000 people and do the average. Just my thoughts. Thanks for yours!

Be aware that astrology is concerned with character and, if I'm correct, events in your life. Not physical health. And each individual has like a gazillion factors hitting on them throughout their life to change the shit out of the star dust poured on them in the birth room.
