Cut From Steel

HE STARTED RUNNING AT 89. HE FINISHED A MARATHON AT 100.

Fauja Singh grew up in a farming village in Punjab, India. By his own account he was born in 1911, though no birth certificate was ever found. For most of his life he farmed and raised a family.

Grief hit him hard in his eighties. His wife died in 1992. A son was killed in a construction accident two years later. Singh moved to Ilford, in east London, to live with another son.

Singh took up running to get through the grief. In 2000, at a claimed age of 89, he finished the London Marathon in 6 hours and 54 minutes. He kept going. In 2011, at a claimed age of 100, he crossed the finish line in Toronto after more than eight hours on the course.

Guinness never certified the record because the paperwork did not exist. Singh did not seem to care. His last race was a 10K in Hong Kong in 2013. In July 2025, a car struck him near his home village, and he died.

Singh did not have special legs. He had legs he refused to stop using. His story is a reminder that legs answer to use, at any age. Today's letter is about what may be happening inside yours when walking starts to hurt.

Why Does Your Doctor Never Mention It? Pick One.

There is a natural compound that addresses what actually damages arteries. Your doctor has almost certainly never named it in front of you.

Quick: why do you think that is?

▸ A) He has never heard of it

▸ B) It does not work

▸ C) It is too expensive

▸ D) Nobody makes money finding it

Most people pick A or B. The answer is D, and the chain is short.

It cannot be patented. No patent means no monopoly. No monopoly means no rep walking into the exam room with a free sample and a glossy brochure. So it stays off the checklist. Year after year. Doctor after doctor.

THE ACHE YOU WALK OFF

You park at the far end of the lot and start walking. Two blocks in, your calf starts to burn and cramp. You stop, pretend to check your phone, and the ache fades. Then the same thing happens on the way back, and you blame the shoes.

I know what you call it. You call it getting older, or a bad knee, or arthritis. The American Heart Association says many people think leg pain is a normal part of aging. Sometimes it is something else.

You may have built your days around it without noticing. Elevators replaced the stairs. Your evening walk got shorter, then stopped.

IT'S NOT AGE. IT'S YOUR ARTERIES.

You may have this pattern even if nobody has named it for you. Doctors call it claudication, and it is a classic sign of peripheral artery disease, or PAD. Three things make it worth taking seriously.

01 / It is more common than you think

About 8 to 10 million American adults have PAD, according to the American Heart Association. Many have no symptoms at all. Others have the walking ache and blame it on age. Smokers may face up to four times the risk.

02 / Your legs are a window

PAD means fatty plaque is narrowing the arteries to your legs. Plaque rarely stays in one place. The AHA says PAD raises the risk of heart attack and stroke. In other words, your calves may be telling you something about your heart.

03 / The test is simple

The ankle-brachial index compares the blood pressure at your ankle with the pressure in your arm. Checking takes about 10 to 20 minutes, using blood pressure cuffs and a small ultrasound probe. It feels about like a routine blood pressure check. A reading of 0.90 or lower points to PAD.

WALK INTO THE ACHE

You might expect a doctor to tell you to rest. The 2024 guideline from the American College of Cardiology and the AHA gives structured exercise its highest rating instead.

Harvard Health describes the method. You walk until the pain starts, rest until it eases, then walk again. The usual target is at least 30 to 45 minutes, three times a week, for at least 12 weeks. A Cochrane review found supervised programs added about 180 meters to how far people could walk.

You will not walk this off in a week. Most programs run three months, and the gains build slowly. Treat each walk like a rep at the gym.

I would ask your doctor about an ankle-brachial index if you smoke, have diabetes, or are over 65. Diabetes and smoking are the two big ones to mention. Ask sooner if your feet stay cold or a sore on your foot will not heal.

I would rather you find this in a doctor's office than in an ambulance. The test is simple compared with what it can warn you about.

One last thing. Your legs may not be worn out. They may be short on blood. Find out.

6 free habits that keep the blood moving:

You didn't put in 45 years to settle for beige.

01 / SUV · Range Rover Sport

Land Rover revealed the third-generation Range Rover Sport in May 2022. The 2026 model starts at $79,450 in the US. It rides like a luxury sedan yet still handles a muddy track. Park it at the trailhead and let your legs do the rest.

02 / Gear · GORUCK Rucker

Jason McCarthy, a former Green Beret, founded GORUCK in 2008 with his wife, Emily. The Rucker is a pack built for walking with weight, with a sleeve that holds a ruck plate. Today's Rucker 5.0 runs about $265. Start light and add weight slowly.

03 / Drink · The Dirty Martini

A dirty martini is gin or vodka with a splash of olive brine, garnished with olives. One story credits a bartender at the Waldorf Astoria with putting olives into a martini. Serve it very cold, stop at one, and drink a glass of water alongside.
