This is a good callout, and it is true that most hand sanitizers are not effective against norovirus.

However, at the risk of sounding like an advertiser which is not my intent, there are some higher grade sanitizers out there that do kill norovirus. One is called “Prime Defense” and was originally developed for cruise ships and restaurants where norovirus outbreaks are a major concern. Companies are not allowed to advertise kill of specific pathogens like norovirus for products regulated by the FDA, hence why it is not advertised as killing norovirus (hand sanitizer is an over-the-counter drug regulated by FDA).

Washing your hands properly with soap and water is still an effective way to reduce risk of norovirus.

Your second sentence made me think of this.

Parts of my thesis were definitely written with “Goodbye Horses” on loop (you know from that one scene in Silence of the Lambs). Not sure what that says about my vibes in grad school.

It’s $3 per month for 200GB for me currently in the US.

I didn’t know about logarithmic perception, that’s interesting! I bet you’re right about 7x being chosen due to the significance of the number seven in the Bible.

I was curious about this too. From random web searching (Syfy.com), the sun is 200,000 times brighter than the moon in the visible light region of the electromagnetic spectrum.

Found out yesterday that a McDouble is $3.49 here which is crazy to me.
