My impression is that German car brands usually do not focus as much on 0-60 accelaration as much as Tesla does. Especially for a Porsche, it's more about handling than drag race performance.

Your statement only applies to the subset of countries where there is judicial independence.

Glycemic Load = GI * carbohydrates (g) ÷ 100. Accordingly, the GL in the example would only decrease if fat replaced some of the sugar. GL does not consider the totality of food intake but can be calculated for individual foods. (https://www.gisymbol.com/what-about-glycemic-load/)
What you are referring to may be the glycemic response, which, apart from GL, also depends on the intake of fat and protein among other things. Adding fat and protein does indeed reduce the glycemic response:
"It is generally accepted that adding fat and protein to carbohydrate reduces glycemic responses by delaying gastric emptying and stimulating insulin secretion (1,2). These effects have a number of possible implications for human nutrition, such as supporting the role of high protein or high fat diets in the management of diabetes (3,4) or being a source of criticism for the application of the glycemic index to mixed meals (1,5)." https://academic.oup.com/jn/article/136/10/2506/4746688

So which characteristics do you describe when you're asked to describe a person? Which features do you imagine? The shape of their head?
I would assume that most people have some form of non-visual, database-like memory for each person.
(I sometimes lose the ability to recognize people when they change their haircut, when they wear a different type of clothes, or when they meet me in an unfamiliar setting.)

While I previously thought I might have aphantasia, I now tend to think that most people lack the ability to imagine face or other complex objects. HN threads tend to confirm this.
In other words, while I can't imagine my family members' faces, I also don't think many people can.
If not proven otherwise, I now assume that most people forget the visual memory of faces after a few seconds while preserving the ability to recognize people.
Obviously this excludes people with photographic memory.

For comparison: Harvard Healthy Eating Plate
https://www.hsph.harvard.edu/nutritionsource/healthy-eating-...
At least among the Harvard faculty, there appears to be a consensus that healthy fats are important, which the Canadian guide doesn't seem to stress that much.

Comments on the Harvard Healthy Eating Plate (https://www.pbs.org/wgbh/pages/frontline/shows/diet/intervie...):
INTERVIEWER: Some nutritionists have criticized your pyramid as "floating on a lake of olive oil."
WILLETT: The formal studies that had compared a more moderate fat intake as we've suggested, with low-fat diets, have actually consistently shown that people did as well or better controlling their weight on a moderate-fat diet compared to a high-carbohydrate, low-fat diet.
INTERVIEWER: Even good fats are more fattening than good carbs. So they think you're contributing to the obesity epidemic, or there's a risk of that. A tablespoon of olive oil is 14 grams of fat.
WILLETT: There are all kinds of beliefs about the amount of fat in a diet, tremendously strong opinions. What we really need is sound data, and the studies that have been done show that people actually end up controlling their weight at least as well, and usually better, on moderate-fat diets compared to low-fat, high-carbohydrate diets.
INTERVIEWER: Is it okay to get more than 30 percent of your calories from fat?
WILLETT: The evidence is quite clear that it's perfectly fine to get more than 30 percent of your calories from fat, and probably, in fact, it's even better to be getting more than 30 percent of calories from fat, if it's the healthy form of fat. ...

That's my own experience as well. I would guess that this is how most people experience 'imagination'.
Same with faces: I guess nobody can really 'see' a face in their imagination, at least not for more than a few seconds of high-resolution short-term memory. They can, however, use their knowledge about nose shapes etc. to construct a symbolic model of the face in their mind.

If Apple doesn't expect to achieve a satisfactory return on investment they shouldn't enter a new business area, regardless of their liquid assets ('money reserves').
If expected ROI is too low they should return the money to investors (share buyback or dividends) and let investors choose a different investment with better prospects by themselves.

> By the way - 10% in 3 years would be a perfect milestone to 100% in 30 years.
That would be a reduction to about 35% of the original after 30 years.

This looks like a textbook example of spurious correlation, great for introductory courses in statistics.

Why do they not replace the kiosks with QR codes on the dining tables? You scan the code and order directly from your smartphone.
That's the experience I know from China. Are there any restaurants in the US that do it similarly? Or perhaps not due to the lack of WeChat and suitable payment providers?
