For those who demand more ad: An archaeologist found a 4,500-year-old map of the inside of a man's head

4,500 years ago, an Egyptian painter drew a map on a tomb wall south of Cairo. Not of the Nile. Not of the stars. Of the inside of a man's head, with one spot in the dead centre marked by the Eye of Horus. I'm the archaeologist who brushed the dirt off it this March. At the lowest point of my career. Science has a name for that spot now. It's why, at 47, I'd started losing words in front of rooms I used to own. Let me back up, because the map only makes sense if you know how bad things had got. I'm 47. I live in Bristol with my wife Jo and our two kids. For 22 years I've been paid to spend four months a year in Egypt on my knees with a brush. People think archaeology is Indiana Jones. It's mostly paperwork. Every season lives or dies on a funding bid, and every bid lives or dies on one 40-minute presentation to a panel. I'd done eleven of them. Never lost one. Last September I stood up in a wood-panelled room in London, clicked to slide 3, and the word I needed just wasn't there. "Stratigraphy." A word I've said ten thousand times. I stood there with my mouth open while six people looked at their pens. They funded the season. They gave it to Daniel to run. Daniel is 32. I trained him. I told Jo they wanted "fresh legs." She gave me the look she'd been giving me for about a year. The look you give someone you're worried about but don't want to say it to. Because it wasn't just the panel. I'd sit down at 8 to write a site report and look up at 10:15 with one paragraph. I'd lose the end of a sentence halfway through saying it. Jo would ask me something at dinner and I'd realise she'd asked twice. And the one that scared me most. I'd stopped noticing things. In my job, noticing is the job. The odd colour in the soil. The chisel mark that shouldn't be there. I used to spot it before anyone. Now the students were pointing things out to me. I did what blokes do. Blamed my age. Blamed the travel. Cut the wine to weekends. Started running again. Bought the lion's mane everyone on the podcasts swears by. Drank enough coffee to drop a horse. Nothing moved. In March I flew out as Daniel's site supervisor. My pride went in the hold with my luggage. Week three, he sent me to clear a side passage everyone had written off. Low ceiling. Nothing on the old plans. The job you give the old guy. About 4 in the afternoon my head torch caught a patch of red under the grime. It took me two days with a brush. A man's head, side on, sketched in red ochre the way the painters marked up a wall before the carvers came in. A line ran from the eye straight back into the skull and stopped at one small dot in the dead centre of the head. Around the dot, they'd painted the wedjat. The Eye of Horus. It wasn't decoration. There were measuring ticks along the line. It was a map. Of where to look inside a man's head. I sat on the floor of that passage for a long time. I knew what sat on that spot. Every crank on YouTube has told me. The pineal gland. The "third eye." For 22 years I'd rolled my eyes at all of it. That night in the dig house I couldn't sleep. So I did what I do with anything I dig up. I went looking for the evidence. By 3am I'd stopped laughing. The pineal gland is the size of a grain of rice and it sits in the exact centre of your brain. Right where the line on that wall stopped. The "third eye" bit isn't as mad as it sounds. In some lizards a close cousin of this gland is wired to an actual third eye on top of the head, with its own lens and its own retina. In us it's buried deep, but it still runs on light. It reads day and night through your eyes and sets your body clock. When to sleep deep. When to wake up switched on. Two things about it I couldn't unread. One. It sits outside the blood-brain barrier. Most of your brain has a security gate that filters what gets in from your blood. This gland doesn't. And gram for gram it gets one of the richest blood supplies in your whole body. Whatever's in your blood hits it unfiltered. Including cortisol, your stress hormone. Every deadline, every 2am inbox, for 20 years. Two. It turns to stone. Literally. Scans show calcium crusting over it in a huge share of adults, and it gets worse every decade. Researchers have linked that crust to worse sleep and a weaker body clock. Then modern life piles on. Screens till midnight telling it the sun never set. Broken sleep. Another deadline. Repeat for 20 years. That's what we have been calling "getting old." Twenty years of cortisol hitting a gland with no gate. A body clock that never fully switched me on. And a gland all of us laughed at, slowly turning to stone. I started calling it the stone eye. Whoever painted that wall didn't have the biology. But somebody, 4,500 years ago, knew exactly where to point. I flew home in April and told the whole thing to the one man I knew wouldn't laugh. Rich. We shared a flat at uni. Quantity surveyor, 48, the most switched-on bloke I know. Four years ago Rich thought he had early-onset dementia. He got lost driving to his own office. He told me over a pint and I had no idea what to say. He's been promoted twice since. He listened to all of it. Then he said, "You can't chip calcium off a gland, mate. Nobody can. But you can stop feeding the fire." That's what he'd done. Three things. Bring down the cortisol that's been hitting it. Get the blood flowing properly to your brain again. Feed your brain the raw materials it's been running out of. Then he reached into his gym bag and put a bottle on the table between our pints. "Two with breakfast. Phone out of the bedroom. Get outside before 9. And don't research it for three weeks. Just do it. For me." The bottle was Genius Mind, from a British company called JustFloow. I researched it that night. I'm an archaeologist. It was formulated by Shona Wilkinson, a registered UK nutritionist, and it lines up with Rich's three things almost exactly. For the cortisol: Bacopa at 11:1, studied for lowering it, with phosphatidylserine alongside. For the blood flow: Ginkgo at 50:1, one of the most studied plant extracts on earth for getting blood to the brain. For the raw materials: tyrosine, choline and a full set of B vitamins. 16 ingredients in two capsules, made in a GMP-certified facility in the UK. That's when I saw why nothing had worked. The lion's mane, the coffee, the running. All of it was pushing a tired brain harder. None of it took the hit off. Week one, nothing. Slept a bit deeper. That was it. Day 11, I sat down at 8 to write up the passage. When I looked up it was 10:40 and I had 3,000 words. Week three, Jo asked me something at dinner and I answered the first time. She noticed before I did. "You're back," she said, and went quiet. Week five, I was going through my photos of the wall and saw a second, fainter line under the first. Running from the dot down to the back of the neck. I'd looked at that wall every day for a fortnight. So had Daniel. Neither of us had seen it. Nobody can explain that second line yet. That line is what I took to the panel. Week seven, I went back in front of the panel. For the first time in two years I actually wanted the room. Same faces. 40 minutes. No notes. Every word where I'd left it. They funded a new season. My name at the top. I'm writing this from the dig house. Generator humming, team asleep. Daniel's on my team now. He's brilliant, and I told him so. And the director's day rate is nearly double what I was on as a supervisor, which Jo and the mortgage have both noticed. The money's nice. It's not the bit I'll remember. It's walking back into that passage in October and seeing things on that wall I'd have walked straight past a year ago. If you're a man in your 40s or 50s and you've started losing words, losing mornings, losing the edge you built your whole career on, you're not getting old. There's a gland the size of a grain of rice in the middle of your head, taking every hit your bloodstream throws at it, with no gate. The stone eye. Nobody warned you about it. The Egyptians drew a map to it. You don't need a head torch. You just need to stop feeding the fire. 👉 https://justfloow.com/pages/genius-mind-pineal EDIT: loads of messages asking where to get it.
