I learned touch typing some 15 years ago with "The Typing of The Dead" from the dreamcast era. This game was full of drills to make you practice every aspect of typing: accuracy, speed, etc. Also it made you practiced your worst keys which was very helpful for me.
I would have liked to see this kind of game used to learn other skills but I never saw anything like it.
I also hoped that AI/deep learning could assists us in learning new skills but it's not yet a thing apparently...
I found the first two articles were interesting despite obvious flaws in the presented evidence. After reading the third one, it just looks like logical fallacy to me.
For example, taken from the first article:
> In the past, most people got slightly leaner as they got older.
How can you claim that with so few data. From the same data I would conclude that obese people die at young age...
I don't think we should exclude any possible cause but a global contaminant which is the only cause of obesity seems far fetched.
Simple logic would suggest that our food is the main culprit.
Personaly I would bet obesity is due to weakened gut microbiome (due to consumption of process foods), transmitted from mothers to their children. In other words, each generation consuming processed food gives birth to children more susceptible to obesity. It has actually been modeled with rats (cannot find the published link though).
> Primates and rodents living in research colonies, feral rodents living in our cities, and domestic pets like dogs and cats are all steadily getting fatter and fatter.
All are fed with human produced food. Also as someone noted our food (raw food) is decreasingly nutritious when it comes to micronutrients and vitamins.
Also if you want to level up your skills, and learn about learning in general, these are some books you should check:
- Practice perfect
- Peak
- A mind for numbers
- The inner game of tennis
- Guitar zero
- The art of learning
