What Your Age REALLY Measures” — Feynman on Timekeeping

Описание: Your age feels like the most basic fact about you.

A number. A count. A simple measure of “how long you’ve been alive.”

But Feynman-style thinking exposes something weird: your age isn’t measuring you. It’s measuring a timekeeping system—a particular way of slicing the universe into repeatable cycles, then counting them.

So what does your age REALLY measure?

In this video, we follow the idea all the way down:

Why “years” are not fundamental units of reality

How calendars are built on cosmic motion, not human meaning

What it would mean to measure age in heartbeats, sunrises, or atomic vibrations

Why physics treats time as what clocks do—not a mystical river flowing

The unsettling takeaway: you’re not “getting older”… you’re counting cycles in a changing universe

By the end, “I’m 30” or “I’m 45” won’t feel like a personal label. It’ll feel like a coordinate—one that depends on how you chose to keep time.

Watch to the end and comment: If you had to measure your life in one unit (breaths, meals, sunsets), what would you choose?
