Boys and Girls

According to the article, you can control the
sex of your child by the profession you choose. At least in this
group of friends i would have to say that there are probably
going to be a lot of boys. Engineers , computer scientists and
scientists , cant see many girls.

Does this hold true for you ? On my mum's side.
Dad - engineer - mum - house - 2 boys
Uncle - doctor - aunt - teacher - 1 boy 1 girl
Uncle - doctor - aunt - admin/house - 1 boy 1 girl
Uncle - engineer - aunt - science - 3 boys

May be there is some truth ?!
