Why YSK: People seem to, on average, think that a car takes a lot of fuel to start up. In reality, it takes on the order of a few millilitres of fuel to start an engine. That means if your car isn't equipped with an automatic start/stop system to stop your engine instead of idling, it saves fuel to turn off your engine and start it back up when you need it.

Caveat: air conditioning and radio might not work with the engine turned off.

Scenarios where this might be useful include waiting for trains to pass at rail crossings, waiting for food at drive-throughs, dropping off or picking people up on the side of the road when they need to load stuff, etc. May not be a good idea to use this while waiting at a red light because starting the engine does take time which would annoy drivers behind you when the light turns green.

Some cars are equipped with systems that will automatically stop the engine when you are idling for a while (e.g. waiting for a red light). If yours is, then manually turning off your engine will probably result in reduced fuel savings compared to just relying on the car to do it for you.

Why YSK: ERs are there to quickly and efficiently find emergencies and treat them. If no emergency is found then their job is done. It is the patients' job to follow-up with their primary care or specialist for a more in depth workup should their symptoms warrant that.

I'll give a quick example. A patient presents to the ER for abdominal pain for 3 months. They get basic labs drawn and receive an abdominal CT scan and all that's found in the report is "moderate retained stool" and "no evidence for obstruction or appendicitis". The patient will be discharged. Even if the patient follows their instructions to start Miralax and drink more fluids and this does not help their pain, the ER did not fail that patient. Again the patient must adequately follow up with their doctor. At these subsequent, outpatient appointments their providers may order additional bloodwork tests not performed in the ER to hone in on a more specific diagnosis.

Why YSK: Back in 2020 when Australia had our massive wildfires I still had to drive to work everyday in the smoke. I also went and got my car serviced around the same time and they showed me how dark my cars air filters had gotten after just a few weeks of those conditions. The air filters in cars aren't designed to filter out so many particles so as soon as you can you should get them replaced.

It’s 1900s, not 1900’s. You only use an apostrophe when you’re omitting the first two digits: ‘90s, not 90’s or ‘90’s.

Why YSK: It’s an incredibly common error and can detract from academic writing as it is factually incorrect punctuation.
