For those interested. Here is what I do to keep the brain/body sharp for hours of chess.

Thanks for the feedback...
I was very athletic when I was younger... My main sport was a long distance runner... Now my knees complain at the pounding, so I prefer Latin style dancing... It's a fun workout for me...

Its perfect. Natural movements. Nothing extreme so you dont get injuries. I have so many injuries from elite level training its not even funny. I have to be very careful with what I do now. I teach in my own Dojo still but movements are very controlled. I dont do fighting anymore. Just teach techniques.
In fact I really enjoy Table Tennis these days as well as its much easier for the body to do for me. Yet still train those fast reactions and swift movements. So far its injury free for me.
But im a total potato when it comes to dancing haha. Wife wanted me to do Salsa with her. Went once and then I dropped out. Stepped on too many toes haha.

win-win on the exercise to fun ratio...
Ut-um... you need to jump back into that dancing class... try bachata... it is slower and has and easier step count... I learned bachata before salsa and was glad I did... Salsa is a lot harder because it is fast and unforgiving. With bachata, if you mess up, you can usually get back into rhythm pretty quickly.

I already learnt the lesson to not start right away in the middle of the night, rather at 6am or 7am. Having about 18 hours to play with fewer disruption of biorhythm gives better chances to have some little bit left in the tank when it finishes.

And yes one normally takes short breathing times at least

Methyline Blue for cognitive boost
I know of Methylene Blue, but not for cognitive boosts. Do you inject it? Or does your doctor do that every now and then?

books has been written about this compound
Not so much that I could find them. Can you recommend one or more of those books?

Also note that Methylene Blue is used as a placebo, which would be an odd choice if it really worked.

I read the one written by Mark Sloan. Its ok but basic.
there are many books on this compound:
https://www.amazon.com/s?k=methylene+blue+book&ref=sr_nr_p_rk_sp_3
Once you feel it on your self you know why they write so much about it.

No its usually orally intake.
Some do provide it as IV but to me its pointless as you take it daily.
I did not know its used as placebo. Not even mentioned in books interviews and articles. Would be counter productive considering its huge broad spectrum uses.
Its been around since 1876.
Anyway some feel resistance to this drug while they have no issue drinking coffee or beers. Or take antibiotics when they get sick. Painkillers if headaches etc. So its more of a cultural programming than actual safety concerns.
If we knew whats in our foods we would see the concerns are out of proportions with reality.
Just make sure if you do get some get the more expensive USP grade. also called pharmaceutical grade.

Here is some anecdotal things I experience with it:
Heart rate has dropped by about 10 beats pr minute due to increased oxygen uptake.
My Spo2 went from 95 to 98% consistently.
Doing cardio is much easier.
Breath hold doing breath work is much longer. Co2 resistance is increased dramatically.
much more energy throughout the day.
brain can multi task and think clearly.
Im being nicer as a person. It does something to dopamine and serotonin.
more feeling of happiness. resistant to negativity overall.
I eat less for some reason and have lost a bit of weight, but not muscle.

thats just my own observations but the list of benefits researched is a long long list worth looking into.
I totally get this is by far not for everyone. for some it is. just keep an open mind.
