What is a topic that you are passionate about but never gets brought up in conversation?

You need a licence to marry, to drive, to work in many industries, to operate heavy machinery, to operate a boat, etc, but any fool can decide to be a parent. No training, licensing, and virtually zero supervision, it’s just treated as an ‘instinctive’ behaviour. In fact it’s the most critically important thing we do as a species, and too many are failing miserably at it.
