To break this asrology hex on him (and maybe you), find out a few examples of really famous people also born on his birthday -
I say odds will have it that there is great diversity - for example: In my case, 9/15/49 - other 9/15 people include:
Ettore Bugatti, James Fenimore Cooper, Dan Marino, Agatha Christie, Murray Gell-man, Prince Charles 2nd Son, etc...and these were just the ones I remember off-hand because I liked them.
No rubber stamp there, eh?
