Guy in my gym, fifty-three, pulls more off the floor than most of the twenty-five-year-olds. Last Monday he walked out to the lot, keys in hand, and just stood there.

He stood there two full minutes, then hit the panic button and followed the noise.

He laughed it off. A minute later he got quieter and asked me if this is how it starts.

Probably not. What was most likely going on is more interesting than what he was afraid of.

You did not forget where you parked. Your brain stored that spot just fine.

Trouble is, it also stored Friday’s spot, and Thursday’s.

There is a test that shows what is actually happening inside your arteries right now. Not your cholesterol. What the artery wall itself is doing.

It quietly disappeared from standard checkups.

Not because it stopped working. Because what it reveals would put billions in heart-medication sales at risk.

You will not be offered it at your next physical. You can still find out what it checks for, and you can ask by name.

P.S. Think back to your last three checkups. Nobody ran this one. That is the part worth sitting with

And every Monday for the last six years at that same gym.

Forgetting where you parked is not a storage problem. It is a sorting problem.

Pattern Separation

Your brain’s ability to keep two nearly identical memories apart, so today’s parking spot does not blur into yesterday’s.

That job belongs to a small strip of tissue in the hippocampus called the dentate gyrus. Think of it as the clerk who stamps a date on every file so they don’t all end up in one pile.

When that clerk slows down, you do not lose memories. You lose the edges between them.

Now take that out of the parking lot and into your work week. Two client calls with similar terms.

Two versions of the same deck. The vendor who quoted you Tuesday versus the one who quoted you Thursday.

The man who mixes those up does not look forgetful. He looks unprepared, and unprepared costs money.

What floored me is what that little clerk runs on.

In 2014, a Columbia University team gave adults in their fifties and sixties a drink loaded with cocoa flavanols for three months. Brain imaging showed more blood flowing to the dentate gyrus, and they scored better on a memory test built to stress exactly this sorting job.

Flavanols are plant compounds found in cocoa, tea, apples, and berries. They help the lining of your blood vessels relax, so more blood reaches tissue that is hungry for it.

In 2023 the same Columbia group, working with Brigham and Women’s Hospital, ran it bigger. About 3,500 older adults got 500 milligrams of cocoa flavanols a day, every day, for three years.

The men and women who gained the most were the ones eating the fewest flavanols to begin with. Their memory scores improved roughly ten percent over placebo.

So for a lot of men, part of the slip they blame on age may be a supply problem. The clerk isn’t retiring, he’s running short on what he needs to do the job.

You won’t close that gap with a candy bar. Most of the flavanols in cocoa get cooked out during processing, which is why the researchers used a measured extract and not a chocolate habit.

Food gets you part of the way. A cup of tea, an apple, a handful of berries all count.

Hitting a steady few hundred milligrams every single day from groceries alone is harder than it sounds. A quality, standardized cocoa flavanol supplement is worth a look here, the same kind of measured dose the research used.

One straight line before I let you go. If the slips are getting more frequent, or the people around you notice them before you do, that is a conversation for your doctor, not a newsletter.

But for most guys standing in a parking lot pressing the panic button, nothing is broken. The filing clerk just needs supply.

Tomorrow morning, before the first meeting, swap one coffee for a cup of green or black tea and eat an apple with it. Then start tracking your flavanols the way you already track your protein.

The man who keeps Tuesday separate from Thursday is the one who catches the wrong number in the contract.

Feed the clerk.
