I recall also reading about people in Australia and some other places with diets consisting of harder food for developing babies/toodlers having better jaw/teeth ratios and straighter teeth despite no regular access to a dentist, which kind of corroborates the findings.
In addition to your comment, I would add to include apps that don’t sound “as interesting” or different from your usual picks. Along the way, it helps to be willing to refactor if you see a different way to implement it. This can help turn a routine task into a more interesting challenge.
