Over the years, I have joined a plethora of local groups where specialists of various types (electricians, civil engineers, IPS battery traders, etc) discuss their work. The fun part is that even though almost none of them belong to my industry, I end up learning small hacks and tidbits that help me down the line.

For instance, today I learned why column concrete is only done 5 foot at a time – and exactly what goes wrong if you try to circumvent the limit somehow. In the morning, someone in a fish group showed what Shark Eggs look like (strange and beautiful). A few weeks ago, I learned how Bluetooth Keys on modern cars authenticate.

The world is filled with such fantastic bits of trivia!
