The Research
One approved job. It rescues blood that has stopped carrying oxygen. On memory, the record is thin. Timothy Duong, University of Texas Health Science Center at San Antonio, 2016. Twenty-six healthy adults, a single low dose. Correct answers on a memory task rose about 7 percent. One dose, one day, twenty-six people. It also carries the strongest warning American regulators issue. With common antidepressants it can drive serotonin to dangerous levels. |

The Community
Drops go into a glass of water. Your tongue turns blue for an hour. Users describe focus arriving by mid-morning and no afternoon fog. The story is energy — a spare route through the little power plants inside your cells. Bottles sell for about thirty dollars, and the dose gets measured by eye. Almost nobody starts with a blood test. |

| Spatial Memory |
| Visuospatial memory holds what your eyes just saw. Look away, and the layout should still be there. Today’s game checks how much of it survives. Try to clear it with no second looks. |

A new Exxon is rising, and Wall Street is repricing it
In the 1970s, three oil giants found it. They buried it to protect oil.
Sixty years later, one company finally cracked it.
Google just signed a 15-year deal. The biggest names in tech are moving in fast.
A new Exxon is rising, and Wall Street is still pricing it like a sleepy little energy stock.
That window does not stay open once the crowd wakes up.

| Your stress hormone is supposed to swing |
| Stress gets blamed for plenty. This team measured it instead. Researchers at Rush University Medical Center collected spit from 3,895 older adults. Morning, afternoon and evening, across one ordinary day. Then they tracked how those people thought for eleven years. |
| Let me explain what they were watching. Cortisol is the hormone your body releases under load. It is built to move. High soon after you wake, low by the time you turn in. That daily swing is the signal. |
| Picture a tide. A working day has a high mark and a low mark. The people whose tide moved the most held their thinking best. The people carrying the heaviest load across the whole day slipped fastest. So a flat line was not calm. It was a rhythm that had quit doing its job. |
| |
Average age, 77. Every one of them felt normal on the day they filled the tube. The shape of the day mattered as much as the size of it. |
|
| I could be wrong, of course. Nobody changed anyone’s cortisol here. This is a long look at a group of people, not a trial. And the same patterns did not predict who went on to develop Alzheimer’s. That gap is real, and you deserve to hear it. |
| But the direction looks right to me. I believe a day with a real morning and a real evening gives that rhythm something to follow. Your nights are the half you control. I urge you to take a hard look at your evenings. |

| Sit down on the floor, then stand up |
| A doctor in Rio timed this one. Claudio Gil Araújo and his team at the Clinimex clinic scored 4,282 adults on a single movement. They were 46 to 75, and two in three were men. You sit down on the floor, then stand back up. You start with ten points and lose one for every hand, forearm or knee you lean on. |
| Then they waited. The follow-up ran past twelve years. Among the people who scored a perfect ten, 3.7 percent had died. Among those who scored four or less, 42.1 percent had. |
| That is not a memory test. I want to be straight with you about it. The study counted deaths, not diagnoses. But it reads the legs, hips and trunk that carry you around all day. And a body that stops moving well rarely leaves your brain out of it. |
| Treat the number as a reading, not a verdict. |
| The Protocol |
| When |
| Once this week, then again in three months |
| Duration |
| Thirty seconds |
| Rules |
| Bare feet, clear floor, nothing in reach to grab. Cross your legs and lower yourself down. Stand back up the same way. Start at ten. Take one point off for each hand, forearm, knee or side of the leg you put down. Take half a point off for a wobble. Skip it if a knee or a hip is sore. A score you cannot get safely is worth nothing. |
| |
| Write the number down and date it. A low score points at legs, hips and a trunk you can still train, so it is information rather than a sentence. I urge you to try it. |

| A kimchi bug that grabs plastic on the way out |
| Two weeks ago we argued about plastic. Particles too small to see, found in human brain tissue, with no way out on offer. This is the first hint of an exit. A South Korean team pulled a lactic acid bacterium from kimchi that sticks to those particles. Germ-free mice given the strain passed more than twice as much plastic in their droppings. Mice, not men. Nobody has shown less plastic in anyone’s brain. And the work came out of a government kimchi institute, which you should weigh. |

| The dark plants showed up in the numbers |
| A memory clinic in Sicily kept food diaries. Ninety-two Italians over 65 filled them in. The ones eating the most plant compounds, the bitter dark-colored ones in berries, tea and seeds, were less likely to have mild cognitive impairment. Two families stood out: flavonoids and lignans. But ninety-two people is a small group. One snapshot cannot say which came first. And their scores on the standard thinking tests did not track intake at all. |

| Eight bat genomes, one blunt lesson |
| Some bats live seven years. Others in the same family live forty-two. A team at Penn State went looking for the reason. Juan Vazquez and colleagues read near-complete genomes from eight North American species. The long-lived ones were not better at patching up damaged cells. They were better at scrapping them. And the genes for aging, for fighting infection and for resisting cancer turned out to be the same genes, moving together. Bats, not people. But it argues that aging is one problem and not a list of them. |

| Dr. Eric Topol |
| Cardiologist · Scripps Clinic and Scripps Research, La Jolla · author of Super Agers |
| He is 71 and trains at home. Five days a week, about an hour. Thirty minutes on an indoor bike, then kettlebells, dumbbells, resistance bands, planks and a jump rope. He says he is stronger now than he has ever been. The plate is Mediterranean. Nonfat Greek yogurt, blueberries, almonds and walnuts, big salads, fish. No red meat in forty-five years. Nothing ultra-processed either. His rule is simple: if the ingredient list runs long, it goes back on the shelf. He holds the same bedtime most nights and wears a ring that tracks what he gets. His deep sleep went from roughly fifteen minutes a night to roughly forty-five. And he takes no supplements at all. |
| So which parts would I bet on? The training, the sleep and the food are the best-supported habits in this whole field. The ring is a preference, not a prescription. His reason for the empty cabinet is worth repeating — he is waiting for the data. One man’s routine proves nothing on its own. But nearly everything on his list is free. |
