or rather than going by what you have heard by a couple of people you could look at research that actually states:
In Australia, girls perform similarly to, or better than, boys and more girls than boys complete a high school (Year 12) education and more Australian girls than boys follow a pathway to university professional courses. Today, there are more women university graduates than men.

The women that I have met that are in "traditionally male oriented work"are bloody good at thier jobs. In fact if you are looking at the trades eg plumbing electrician etc you can't bullshit your way through for very long - male or female!
