Michael Nielsen and Andy Matuschak wrote Quantum Country (https://quantum.country/), an introduction to quantum mechanics, with integrated spaced repetition questions. Andy develops Orbit (https://withorbit.com/), allowing other authors to do the same.
I agree with Michael that a lot of the value comes from formulating your own questions based on the source material, but I'm also curious to experiment with author provided questions.
In my humble experience, you gain a LOT from writing the questions yourself, I point that I'm not sure if the author is stressing enough.
There's also the problem with cards that are difficult to memorize, which is something that you don't know in advance, and that's a good thing! It shows you were you should pay more attention, write cards in different forms, etc.
Another hypothesis that I've come across on some alternative health sites is that the increased consumption of polyunsaturated fats is responsible for a decrease in metabolic rate/body temperature.
CICO is true, of course, but it doesn't do justice to how interesting the whole topic of weight loss is. Why do some people need more food to reach satiety, why do some people move more, for example.
To be fair, in the CICO model, everyone on Earth would lose the exact same amount of weight, regardless of any of the factors you mention - or at least, the weight loss we'd experience from truly following the tenets of CICO could easily offset any individual mass modification from food or exercise!
It's also true that you'd get far more, and quicker, weight loss by increasing your distance from the earth instead of reducing the earth's mass, but that seems a little selfish...
+1 on making the yogurt. I have been making L. reuteri yogurt (or fermented milk, technically) for a few months. I started with some BioGaia Gastrus tablets in batch 1 and now just use a tablespoon or two of batch n - 1.
I recommend getting a sous vide device for precise temperature control. Initially, I used a the "Yogurt" function on an Instant Pot pressure cooker and about half of the batches failed, separating into whey and curds.
The article linked by parent says to use new BioGaia Gastrus tablets every 4-5 batches so as not to grow unwanted bacteria. Have you had any trouble reusing the same batch indefinitely?
The yogurt has the same taste and consistency as it did in the beginning, so I haven't had any trouble in that sense. However, it does seem prudent to restart periodically.
I started with Dr. Davis' recipe. It's described in his book "Super Gut" and is also available on his website [1]. My current method is a bit simpler:
- I buy full fat milk in a glass bottle so that I can make the yogurt directly inside without having to sterilize another container. I have had more success with UHT milk than pasteurized milk.
- I add two tbsp. (~40g) of my previous batch to one liter of milk. Close lid and shake.
- Put bottle in a pot of water, submerging most of the milk bottle. I leave the lid on, but untightened so that gas can escape.
- I add a sous vide "wand" to the pot and leave it for 24 hours at 38°C (100°F)
I deviate from Dr. Davis' recipe by not adding inulin to the milk and fermenting for a shorter duration. This probably results in fewer bacteria present in the final product, but the above takes me less than 5 minutes to prepare.
It's a long time since I played it but Real Lives (https://en.m.wikipedia.org/wiki/Real_Lives) might meet your criteria. You start as a child with some random traits somewhere in the world and try to advance your life. Some starts are a lot harder than others.
Very intriguing and interesting concept. Their website (https://reallivesworld.com) really leans into the angle for academic use too. Thanks for sharing this.
Sunlight is one of the most powerful zeitgebers and it makes sense to try and optimize the amount of sunlight exposure. However, is there a difference between morning light and evening light in terms of how they entrain the circadian rhythm?
If I work from 9am to 5pm in a dark office building, permanent standard time might allow me an hour of sunshine before work from 8am to 9am, and permanent DST might have me arriving in work while it's still dark but allow me an hour of sunshine from 5pm to 6pm. Which of those light exposure patterns would allow me to wake up easier at 7.30am?
