What things am I a dumbass about? (lemmy.nz)

Had someone contact me because a browser interface was 'down' and it was actually a cert issue. It surprised me that in an IT context, this person didn't have a basic understanding of SSL certs. They didn't even know how to add a cert exception.

It got me thinking, what basic ubiquitous things am I a dumbass about outside of IT?

Ive seen lots of 'fun facts' compilations, but it would be better to get a wide range of subject suggestions that I can spend 30 minutes each or less on, and become a more capable human.

Like what subjects would plumbers consider basic knowledge? Chemical interactions between cleaning products and PVC pipes?

What would an accountant or a landscaper consider to be so basic its shocking people can live their lives without knowing any of it?

For most areas of expertise, its difficult to know even what the basics are to start with.

The much more general I'd give is don't brake at speed. Well do if you have to, but afterwards look back and see how it could have been avoided with better planning. Outside of a handful of situations (offramps, downhills, some wild speed limit changes, and of course coming to a complete stop) engine braking is more than sufficient for any driver that actually anticipates and maintains a safe following distance. Not only is it much safer, forces you to think ahead, but it also greatly reduces fuel consumption.

It's also IMO the best way to ride a motorcycle spiritedly on the road.

(However you should also know how to perform an emergency stop. Whether you're in a car, on a bicycle, or a motorcycle, get on a straight and train for the hardest possible stop. It might save yours or someone else's life someday. Crazy that some drivers don't even know what their ABS feels like!)
