My factoid of the month is that the word 'man' has its roots as the Anglo-Saxon word for person.Not unlike the female Yeoman of Signals who's recently joined us. Thankfully, UK Mil hasn't gone over completely to gender-neutral naming (yet).
To modify for gender required a prefix: a male was a 'waepman' and a female was a 'wifman.' So, the literal translation of, say, chairman, is chairperson.
Every day a gender neutral school day.
