Scrolling down, reading news of the galaxy. The sun will last at most another five billion years when it will run out of fuel, become a red giant incinerating its own planetary system—us. Earth, our moon, our known fellow-planets and their myriad moons, whatever else wanders in interstellar space, vaporized—who cares about the exact science—it’s  the  fact there’s a predictable kapow versus an imagined eternal existence. This puts our solar system’s lifespan roughly at its midpoint, a point my own life can no longer be said to occupy. Middle-aged galaxy. I’m at the 2/3 point at least. Another 30 not-improbable years to go before my own for-sure demise. In planetary years, I’m older than the sun, a good second half of its life still ahead, and Earth’s with it, barring incoming asteroid or global self-annihilation. My god, I am older than the sun.
