Researchers studied the effects of a 20-minute walk on the cognitive performance of a group of children.
This is fascinating…
Reading comprehension performance was significantly better after exercise.
Spelling and arithmetic performance were better, though the results were not statistically significant.
Researchers concluded:
“Single, acute bouts of moderately-intense aerobic exercise (i.e., walking) may improve the cognitive control of attention…and further supports the use of moderate acute exercise as a contributing factor for increasing attention and academic performance.”
One other conclusion from the paper:
"These data suggest that single bouts of exercise affect specific underlying processes that support cognitive health and may be necessary for effective functioning across the lifespan.”
I started walking 10x more in 2022 after the birth of our son.
Averaged about ~2-3k steps per day in 2021—averaging about ~20k steps per day in 2022 since May.
Having a kid —> walking more —> living longer and better
(or something like that!)
I have two types of walks:
Active Walks:
• Listening to something or thinking about something
• 30-60 minutes
• Brisk pace
Passive Walks:
• No technology
• Mind free to wander
• 60+ minutes
• Slow, leisurely pace
I find that both have a clear, necessary role in my life.
The Active Walks are typically done at Zone 2 HR level (often wear a weight vest during these to get to that level if flat terrain).
This allows me to easily hit the 180+ minutes per week that @hubermanlab recommends we all get.
I also used to get a TERRIBLE bout of drowsiness after lunch.
I started taking a 10-minute walk immediately after eating and it has worked wonders for keeping my energy steady into the afternoon.
More effective than the large black cold brew I used to rely on for that purpose.

Random question that I’m genuinely curious about: Why don’t commercial airplanes have an eject button?
Like a button that can be pressed if the plane is about to crash that shoots off the top and every seat ejects with a little parachute.
Is it a cost issue? Engineering impossibility?
I have to imagine people would pay more to know they had a better (say 80% higher) chance of survival in the event of a catastrophic failure.
Just something that I’ve always wondered about and now I want to know the answer to.
Even if you assume it still has some hazards and issues (in air collisions post ejection, parachute deployment issues, etc.) if you could get to 80% survival rather than ~0% survival in a catastrophic failure, I bet people would opt to fly a more expensive airline that had this.
The only logic I can think of is that it’s so rare that it’s not worth putting money behind fixing.
But if people would pay for it, why not?
The fear of crashes is outsized relative to their incidence, so I bet there’s a premium/margin to be made on offering this.
