I thought I was pretty thoughtful on replying to the post with the 'studies'....and if you'd remember my response to some of those group 'studies' from an earlier thread, you wouldn't be making such a big deal of it now.
Just goes to show how repetitively petty you are...more smoke in mirrors!
As to TIA's question....consider this...you are basing your question on flawed findings from agenda driven 'studies'...these are funded to 'find' certain results, but ALWAYS leave a door open...because, in reality, they are flawed and skewed results and findings. Only one of the 'studies' posted by Don, even approached what I've been saying..but they glossed over it, turning attention to the (never found) genetic link.
...and if I remember an earlier question of yours correctly, about your family relation, and what you said were the circumstances during the time of a pregnancy, you WILL find that the answer to your inquiry has more consistencies with what I've been saying, than any 'genetic' rhetoric!!
...and that is the plain truth...and I think you know it...and with all the condoning of 'it's in the genes, nothing can be done about it' rap, it leaves one without any answers to correct the things that caused the pain, to cause the issue at question.
(My, that was answered delicately).....

Best Wishes, Hope things come around, (there are some conciliatory open wounds, in your family that should be addressed and healed.)
