straight spine on us=girl and curved=boy

[Inky]

I'm pretty sure this isn't true, but I wanted to see.

Was your baby's spine curved or straight on u/s?
Did you have a boy or girl?

NOT TRUE. The only way this could be true is if men were walking around with superstraight spines all the time and women were all hunched over or vice versa. There is no biological reason why this would be true. Spines are made to straighten and also curl.
