Whatever I earn, my employer pays an additional 17% of that to my super (agreed amount under a union). The national minimum is 11.5%. It’s not taxed and it’s invested in funds that make it snowball to large sums at retirement age.
You’re allowed to withdraw some of under certain circumstances and it won’t be taxed then either.
I work in statistics and we never use girl of woman, only female. The line is vastly different in age and meaning depending on culture, religion, law, or heritage. Even in western societ, 13, 16, 18, and 21 are all valid before tipping to 40, 50, 60, 65, 68, and 70 where the term can be prefixed with some form of adjective.
It’s old-fashioned. Just say female and every culture/society understands you without confusion or insult. Save you embarassing/insulting people while travelling too.
