How is the brain and the military alike? Less is more. By that I mean for the brain, it isn’t about working hard, its about working efficiently, since studies show the better a person is at a task, the less the brain works to perform it. And for the military, it isn’t about bringing more firepower, it’s about putting minimum firepower precisely on the target — again, it’s not about working hard, its about working efficiently.
And I don’t think those are the only two areas where this applies.
Exercise isn’t just good for your muscles and heart – it’s good for your brain, too. One thing that’s struck me about aging (now that I’m feeling the effects) is how the maintenance requirements just keep increasing. One way to stay young is through exercise. Not only does it keep your muscles from atrophy, it keeps your brain from atrophy. Aerobic exercise is best for your cardiovascular system and your brain. Researchers can measure this both functionally through cognitive testing and also physically. People who exercise don’t lose as much grey matter (neurons and support cells) or white matter (myelin sheaths) as they age than people who don’t exercise. So people, let’s get walking out there! We don’t want our brains to shrivel up.
