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.

A pound of peanut butter is around 2600 calories. A pound of Nutella is about 2400 calories. Honestly not as bad as I thought initially.

1 to 2 pounds a week is 370 to 740 calories per day. Eating that much peanut butter for a week or so wouldn’t be too hard, but keeping that rate up consistently would be tough.

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.

This article is talking about benzene, not benzine FYI.

The allowable limit in drinking water by the EPA is 5 ppb. Inhalation exposure limit by OSHA is 1 a 5 ppm per day (inhalation is not an apples to apples comparison to consumption though). I’m not a toxicologist so I don’t know what exposure amount is “safe”, but dosage does matter.

This article mentions benzene coming from the carbomer in these formulas. The benzene is a residual impurity in the carbomer making process, and there are carbomer on the marketplace that don’t use benzene in their manufacturing process, but they are more expensive. I’m not sure the source of carbomer for these products, but I’ve seen reported on carbomer I’ve looked at to have up to 1 ppm of benzene impurity. Products like this might use carbomer up to 0.5 to 1%. So you’d expect maximum levels of benzene to be in the product (at the aforementioned levels) to be 10 ppb. So possibly at double the amount allowable in drinking water by EPA. People drink a lot more water than cough syrup (I hope) so it might not be that concerning.

The article frustratingly does not give amounts of benzene found in these products so it could be sensationalist—I just don’t know. So is benzene bad—yes. Does the cough syrup have concerning levels of benzene? Maybe, but just saying benzene might be present isn’t enough information in my opinion.

I think what you said is true but that also ketchup as a material is shear thinning—meaning as you shake or tap the bottle, this creates stress or “shear” on the liquid which causes the viscosity to decrease. It also takes a little bit of time for the liquid to re-thicken, so it will actually pour pretty well a few seconds after shaking it.

I haven’t heard that before but I don’t work on hair care products very often. Benzyl alcohol is used as a preservative in lots of cosmetic products though. It can be considered an allergen for some people, but overall it’s pretty safe (as far as we know so far).

It looks like the 91% natural ingredients version has benzyl alcohol as a preservative which is typically synthetically derived and in my experience can drastically shift the bio-based ratio.

As far as I can see, the rest of the ingredients are the same, but the sourcing of those ingredients could be different which could also shift the naturally derived percentage.

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

Can’t rule out that the furnace is dying—might be carbon monoxide poison you are experiencing.

Can see the before and after images in this article

“No garage, one space” in Wisconsin winters sounds fun!
