I was born in July but I was born two months early. So not only was I small for my age due to being premature, I was also a late summer birthday so one of the youngest people in my class. I think that can make a big difference, kind of along the lines with the links that @Seymour posted. I'm a 4w5 sx/sp and I've always resided on the melancholy side of things. My dx is bipolar II, which is definitely right.
So, I have just read an article in a scientific magazine according to which traits such as susceptibility for depression,
the body size, life expectancy, etc. are related to the month one is born in.
The factor isn't actually the month of birth but the seasons one has grown up in their mother's belly.
The author of the magazine bases this on several studies. For example the one with the life expectancy is the result of an analysis
of 6 million registered deaths in Germany from 1992 to 2007, stating that people born in autumn and winter live longer than those born in spring and summer.
How about the susceptibility for depression and body size? Tell us about that too :P
I found this quite interesting, so I want to know now, if MBTI, Enneagram or whatsoever is is also influenced by the month of birth.
I'm sorry I can't give a link for the article, since it was published in a german magazine and you would have to buy the whole edition
and pay an interpreter, but you get my certificate that it isn't bullshit.
