Ask an old sailor to find his way across open ocean without a screen in his hand, and he’d shrug and look up.

Celestial navigation was, for most of human history, the only way to cross a sea and know where you were.

A sextant, a chronometer, a set of tables, and the sky. Polaris for latitude in the northern hemisphere. The sun at noon for a clean fix. The moon and the planets when you needed them.

It took years to learn well. Captains drilled it into their officers because getting it wrong meant reefs, rocks, or running out of water a thousand miles from land.

Then GPS arrived

Then GPS arrived, and within a generation the skill quietly slipped away. The US Naval Academy stopped teaching celestial navigation to midshipmen in 1998.

They brought it back in 2015, worried that a cyberattack or a satellite failure could leave a warship blind in the middle of the Pacific. The old skill turned out to be the backup plan.

Shopping wasn’t necessary

And celestial navigation is only one thing on a very long list. Obviously, I am still living. But our British family of seven in the 1950s lived off the land.

Nearly everything we ate was grown in a modestly sized garden or killed locally. The forest supplied wood for heating and water for drinking and bathing.

Home care

Thatching a roof so it sheds rain for 40 years. Coppicing a wood so it produces timber forever without replanting. Reading weather from the shape of clouds and the behavior of birds.

Killing and butchering a whole animal and using every part of it. Sharpening a scythe with a stone in the field. Knowing which plants in the hedgerow will feed you and which will kill you.

Mending. Actual mending, with a needle, on clothes you intended to keep for a decade.

Self-Health

Setting a broken bone in a village where the nearest doctor was three days away.

Baking bread from a starter you kept alive on the kitchen shelf, the way your grandmother kept hers, the way her grandmother kept hers.

All Lost

These skills weren’t lost because they stopped working. They were lost because something faster came along, and the people who knew the old way died before anyone thought to write it down properly.

What would you add to the list? What did someone in your family know how to do that nobody around you knows how to do now? Let readers know what you think
