Well, I used to operate a nuclear reactor…. I was really good at it too.
What skill did you master that you will never, ever use again?
As a child raised in the movie theatre business (I was assistant manager of my own theatre at age 19), I could thread a film projector (Ballantyne Pro35, Teco platter system) in under a minute.

In the summer of ‘88, I had a job where I installed cell phones into cars. No one has needed that skill in over 30 years.

As an elder millennial I was raised to put two spaces after a period. Coming back to academia a few years ago I learn is now forbidden and struggle to break this habit. So it's anyone's guess how many spaces I'm going to put after any given period.

Astronomers double down on claim of strongest evidence for alien life
Are there aliens living on the exoplanet K2-18b? Some astronomers believe they have evidence for molecules on the planet that must have a biological origin, but others disagree

We have not discovered life on K2-18b. We have not even discovered water on K2-18b. All we can say is that the planet does not… not… have an ocean.
