Hello, everyone.
This is Enta.
The other day, I made some parts for a suspended drilling machine.
Did I write that post? Or didn't I?
Did you post that on social media? lol
As I think this, I’m starting to forget even the things I’m sure I wrote myself...
It's seriously crazy, isn't it? (I was actually writing about it, lol)
How about those of you in your late 40s?
My eyesight's getting worse with presbyopia, and my body's starting to fall apart here and there, lol.
It's pretty scary once you're over 50, isn't it?
Are we really entering the era of living to 100?
Wondering, “If I keep aging at this rate, will I end up forgetting everything?” I decided to look up a few things on Chappy!
🧠 ① Changes in Memory
● Areas where the amount decreases
Short-Term Memory (Working Memory):
The ability to "temporarily retain" information—such as numbers, names, and the content of conversations—begins to decline in one’s late 40s.
→ Reason: Decline in the function of neurons in the frontal lobe and hippocampus, and reduced blood flow.
Processing Speed:
The speed at which we understand and process information also slows down year by year.
→ Example: It takes me a while to remember people's names. (This is the base level.)
● Parts That Are Preserved
Semantic memory and episodic memory (= knowledge, judgment, and intuition) areIf anything, it strengthens it...will be done.
Their "pattern recognition skills," honed through years of experience, are superior to those of younger people.
→ Example: The kind of intuition a craftsman has that allows him to “tell just by looking that the underlying rock is poor.”
💪 ② Changes in Physical Stamina
● Muscle and Cardiorespiratory Function
Starting at age 50, muscle mass decreases by about 1–2% each year (especially in the lower body).
Maximum heart rate and lung capacity also decrease.
It takes a long time to recover from fatigue.
→ Example: It gets tough after pulling an all-nighter or working two days in a row.
● Tips for Maintenance
Exercise three times a week for at least 20 minutes (walking, climbing stairs, light strength training).
About 7 hours of sleep +Protein intake is effective.
Reducing alcohol intake improves sleep quality and recovery.
🧩 ③ How to Balance Memory and Stamina
Exercise increases levels of BDNF (brain-derived neurotrophic factor) in the brain, and
It is said that this has been shown to improve memory, concentration, and learning ability.
→ They say “walking” is “food for the brain”!
We found out that our job is the best thing for our brains, lol!
First things first: protein every day! It's important!!
💪 ① Moving gets your brain moving
In fact, the human brain becomes most active when we move our bodies.
In particular, work like that done by slope workers—which involves “physical labor combined with decision-making”—is,
Apparently, it provides the brain with blood flow and nerve stimulation that you just can't get from desk work!
Blood flow to the brain increases, delivering oxygen and nutrients
A sense of balance, the ability to anticipate danger, and strategic thinking all come into play at the same time
As a result, you’ll be able to switch your thinking quickly and make accurate judgments.
In other words, slope work is"Exercise + Decision-Making + Risk Management"It is a comprehensive brain training program that does both at the same time.
That’s why a lot of people who’ve worked in the field are really sharp. (Well, some of them, lol.)
🧠 ② Working on slopes requires a constant series of “instant decisions”
The wind has picked up → Should we stop or continue spraying?
The rock has gotten harder → Should we change the machine? Or change the bit?
The fine sand particles have changed → Should we adjust the mix slightly?
As you can see, split-second decisions can make or break safety, the production process, quality, and the final product.
Keep your brain working at full capacity while moving your muscles.
This is exactly what makes Hōmenya so great—when you move your body, your mind follows!
🔩 ③ It helps train your “planning mindset”
When you move your body, you naturally gain a bird's-eye view of the overall flow.
As I walk around the site and climb up and down slopes, I’m constantly keeping track of things like “material storage areas,” “work sequences,” and “safety distances” in my head.
This repetition helps develop a “planning mindset.”
The habit of thinking on the go is more practical than any management meeting.
🌿 ④ Backed by scientific evidence
Recent studies have shown that aerobic exercise improves memory and judgment.
It helps you absorb new information and generate ideas.
I also find it easier to come up with blog ideas when I'm out in the field!
I just can't come up with anything when I'm sitting at my desk in my chair, lol.
In other words, working on a slope is, in itself, a form of mental stimulation.
"Slope workers are craftsmen who think with their bodies."
Think on the go, make decisions based on your feelings, and work up a sweat as you find the “right answer.”
As long as I can keep moving, it’s proof my brain is still firing on all cylinders! Out on the slopes again today—my brain’s really sharp.
Not only is it scientifically proven, but those older craftsmen who work on slopes are really energetic and smart, aren't they!
The only problem, though, is that I can't quit my job as a slope engineer (I can't retire) lol
I'll stay a slope contractor until my very last breath!
Working on slopes is the best job ever!! lol
See you later.
By the way, if you keep taking protein, you'll feel great!
I drink it all the time, too.
I buy it at convenience stores, and I also drink it at home using a shaker!
