The daily crossword takes under fifteen minutes now, and nothing gets looked up. No dictionary tab open in another window, no guessing and moving on to the next clue. I started that habit years ago hoping it would protect my cognitive health after fifty; on its own it did roughly nothing, but how fast I finish it lately has become one of the steadier entries in my brain supplement tracking log. Readers ask me some version of the same question every week: is this normal aging, or is it something else? A year and change spent treating my own brain like a second set of books has given me a way to sort that out, even without a medical degree behind it.
None of what follows makes me a doctor, a neuroscientist, or any kind of licensed health professional — I need to say that plainly, the way I'd flag an audit exception before anyone relies on the numbers. I'm a retired accountant with a spreadsheet that has more tabs than any tax return I ever filed, and opinions built from a year of testing brain supplements on myself and writing down what actually happened. Nothing here replaces an actual doctor, especially where your own health is the asset sitting on the line.
Is This Normal Aging, or Something Else?
Most of what worries people after fifty turns out to be normal wear, and only a slice of it is real decline. I spent thirty years clearing the 4 CPA Exam sections without a single blank stare under pressure, so losing a longtime client's name mid-meeting hit differently than ordinary turnover — it felt like a hole in a balance sheet that used to close every month without fail. Normal aging tends to look like slow retrieval rather than a missing file: the name is still in there, and it surfaces twenty minutes later while you're doing something else entirely. Real decline behaves differently. The file doesn't come back at all, and it happens often enough that you can't wave it off as one bad afternoon.
The Line Between a Rounding Error and a Real Deficit
I didn't step back from work because of any rule. The standard retirement age for full social security benefits was still years off for someone my age. I stopped because I no longer trusted my own output the way I used to, and that felt riskier than working a few more years. Everyone loses some capacity here. We start out with something like 86,000,000,000 neurons, though headcount was never the number that mattered to me in this line of work — what matters is whether the system still produces the same output on a bad day as on a good one. I started noticing early memory changes long before I had language for any of it, and logging them the same way I'd log a variance became the only way I trusted myself to tell normal from concerning.
There's a structure involved called the hippocampus, and it comes up in nearly everything written about memory after fifty. I'll be straight with you: I'm not going to pretend I can explain what's happening inside it, because that's not my training and this isn't that kind of site. What I can do is watch what comes out the other end — what I remember, what I don't, and whether the gap between the two is shrinking or growing over time. That's the whole method, dressed up in accounting language because it's the only language I trust.
Why Being Good at Routine Can Hide a Problem
Here's something that took me longer to notice than it should have: the biggest risk after fifty isn't always memory loss on its own, it's how good routine gets at covering for everything else. Thirty years of the same kind of work made certain tasks close to automatic for me, and that efficiency is a mixed blessing. A brain that's become excellent at routine can lose some of the flexibility it needs for anything genuinely new, the same way a company stops investing in a new product once the old one is still selling fine. I noticed this most clearly the first time I tried learning a piece of software with an unfamiliar interface and found myself frustrated within minutes — not because I couldn't remember anything, but because I couldn't adapt to something I hadn't seen before.
That's the trap. Efficiency looks like health right up until someone hands you a task you haven't automated yet.
Questions Readers Send Me Most Often
A reader named Dorinda, a fellow numbers-and-notes type who tracks her own results the way I track mine, once asked me how I know whether a change in my weekly log is real or just me paying closer attention. It's the best question I get, and the honest answer is that I often don't know right away — some of what shows up in week one of anything new is just heightened attention, not an actual shift, and separating the two takes more than a single data point. Another question that comes up constantly is whether losing a word mid-sentence, reaching for it and coming up empty, counts as a warning sign. Sometimes, though it's one of the specific things I check for on my own weekly tests, since it's the lapse people describe to me more than any other. People also ask whether price tells you anything about whether a supplement will actually work, and in my experience it doesn't — what a label promises and what shows up in my numbers are frequently two different documents, and I've learned to trust the second one over the first. When I do sit down with a new label, I sort the ingredients into rough categories before I even think about buying, mostly out of habit at this point. More than one reader has also asked why I don't just trust the first week of feeling sharper. A late cup of coffee can produce the exact same afternoon dip I'm supposedly measuring, and a bad night's sleep does the same thing for entirely unrelated reasons, so a single day's log never gets to count as proof of anything on its own.
Sound Frequencies Moved My Numbers More Than Capsules Did
When a claim sounds too clean, I still call Neil, a former colleague from my accounting years who treats every health claim like an unaudited expense report until it proves itself. That habit has kept me out of a lot of dead ends. Most afternoons I walk the same loop through Klyde Warren Park in downtown Dallas, partly for exercise and partly because it doubles as an informal check on whether the fog is present that day — a rough field test that costs nothing and fits into a life that already has enough spreadsheets in it. Capsules and powders made up most of my testing, with mixed results I won't pretend were uniformly positive. What actually surprised me was The Brain Song, which isn't a pill at all — it's a method built around specific sound frequencies rather than anything you swallow. I was skeptical going in, being a man who prefers hard numbers to audio cues, but my own weekly ratings for focus during complicated tasks moved in a direction I didn't expect once I added it to the routine. I also worked The Genius Song into longer sessions when I was trying to learn something genuinely new, mostly because there's no metabolic cost to a sound file the way there sometimes is with a capsule that leaves you flat by mid-afternoon.
Track Your Own Numbers Before You Panic
My full method is its own long post, but the short version is a weekly memory and focus check, logged the same way every single time so the results can actually be compared month to month instead of just remembered as a vague impression. Whether something earns a permanent spot in that routine comes down to a plain return question: did the change in my numbers justify what the product cost me, month after month, or did it just add another line to a spreadsheet that was already too long. If you want to see what that looks like on paper, I've put my full spreadsheet vs. the fog results up for anyone curious enough to dig through them. Starting your own version doesn't need to be complicated — a notebook works as well as a spreadsheet — but write it down. Memory is a bad witness to its own decline, and a log is the only auditor that won't lie to protect you. Tools like The Brain Song are one option worth a look if capsules haven't done much for you either, but the habit of tracking matters more than which product ends up in the log.
The Real Meaning of Aging Well on a Spreadsheet
I keep my testing setup in a spare bedroom in our house in Plano that used to just collect boxes — an old desk on one side, two monitors that split tracking numbers from research, and a whiteboard slowly filling with ingredient names and question marks nobody's answered yet. Some afternoons the light comes in low enough that yesterday's handwriting on that board looks almost washed out, which is a strange thing to find sentimental about a to-do list. Senior wellness, in my experience, has less to do with chasing the sharpness I had at thirty and more to do with knowing which lapses are rounding errors and which ones deserve real attention. A missed name that surfaces later is a rounding error. A pattern that repeats and doesn't resolve is worth a real conversation with an actual doctor, not another spreadsheet tab. Aging well, on my numbers at least, looks less like winning and more like keeping the books honest.
