[Off Topic] Hsieh Forbes Column: Tips For Staying Out Of The ER

[Off topic] My latest Forbes piece is now out: "Tips For Staying Out Of The ER During The Coronavirus COVID-19 Pandemic".

Here's the opening:

As case numbers increase during the current Coronavirus COVID-19 pandemic, hospital emergency rooms are becoming more crowded. Patients showing up at the ER for possible COVID will add to usual load of patients already there for heart attacks, stroke, acute appendicitis, accidents, “normal” influenza, etc.

So anything you can do to keep yourself out of the ER helps everyone (yourself included).

In that spirit, I’d like to remind folks follow some simple old-fashioned prudent practices...

Super Low Gear

"Here's What a Googol-to-One Gear Ratio Looks Like":

To celebrate being alive for a billion seconds, Daniel Bruin built a machine with 100 gears with a 10-to-1 gear ratio…meaning that the overall gear ratio is a googol-to-one. (A googol is 1 with 100 zeros.)

This machine has a gear reduction of 1 to 10 ^ 100. In order to get the last gear to turn once you’ll need to spin the first one a google [sic] amount around. Or better said you’ll need more energy than the entire known universe has to do that. That boggles my mind.

Koreans Vs. Virus

"South Koreans are using smartphone apps to avoid the novel coronavirus":

Recently developed apps using public government data allow users to see how close they are to where a confirmed Covid-19 patient has been. They can also see the date a patient was confirmed with the disease, demographic data about the patient, and, crucially, some of their location history.

At least one app, called Corona 100m, will also alert a user if they come within 100 m (328 ft) of a location visited by someone who’s had Covid-19.

Developers of such offerings have seen a surge in downloads...

"Left digit bias" is why customers are more likely to purchase an item priced $4.99 than $5.00.  I discuss how physicians' "left digit bias" could affect medical care in older patients, and what patients can do about it.
