With one exception, everything you've written here is excellent and I hope folks put these into effect.

However, I'm not aware of any consistent research showing that isolated brain training games (the kind you get in apps to improve attention, memory, etc) work. One caveat - they DO work, but the research I've seen says you get better and better at that particular game but in terms of cognitive improvements - executive functioning, memory, attention, etc - these don't carry over into other areas of life.

Do you have links to any research to the contrary?

NOTE: I just saw Emrah Donmez' excellent comment. What he writes in general is, in my understanding, in line with the general research. And specifically what he says about "mental stimulation" is also in line with it. Here's his whole comment:

Physical exercise:

Regular physical exercise has been shown to improve brain function by increasing blood flow and oxygen to the brain. It also helps to promote the growth of new brain cells and connections between existing cells. Exercise can help to improve memory, attention, and overall cognitive function.

Mental stimulation:

Mental stimulation is important for maintaining cognitive function and preventing cognitive decline. This can include activities such as reading, puzzles, and learning new skills or languages. These activities help to keep the brain active and engaged, and can help to build new neural connections

.Social interaction:

Social interaction is important for cognitive health, as it helps to reduce stress and promote a sense of well-being. Socializing can also help to improve cognitive function, as it requires the brain to process and respond to social cues and engage in complex social interactions.

Rest and relaxation:

Rest and relaxation are important for allowing the brain to recharge and recover from the stresses of daily life. Getting enough sleep, practicing relaxation techniques such as meditation or yoga, and taking regular breaks throughout the day can help to reduce stress and improve cognitive function.

By incorporating these four types of brain workouts into your daily routine, you can help to maintain cognitive health and improve your overall quality of life.
