International Women’s Day celebrates women’s achievements and raises awareness of the continuing mission towards gender equality.

It’s no secret men and women are different. It’s why we have a whole genre of books and jokes about why “men are from Mars and women are from Venus”.

Mentally, physically and biologically, men and women are simply not built the same way. It sounds obvious, but we have only really begun to understand why.
