Most of my friends from college became dental hygienists or went into retail, a lot went into sales. They all started getting married and having kids and buying homes and I was still living like a college student.
Men are very competent in their workplace - and this is going to sound sexist - women are better at running households and juggling lots of things, kids and scheduling and that kind of thing.
It`s hard enough to work and raise a family when your kids are all healthy and relatively normal, but when you add on some kind of disability or disease, it can just be such a burden.
