I Was Today Years Old When I Learned… (Three New Facts That’ll Blow Your Boots Off)

1. Your Taste Buds Have a Lifespan, and They’re Reborn Like a Phoenix

Most folks think your taste buds are these fixed little bumps on your tongue that just exist.

Nope. They live fast, die young, and get replaced constantly. Each taste bud lives for about 10 to 14 days before it’s retired and replaced, much like a gas station employee who has just witnessed something unspeakable in the bathroom and quits mid-shift.

So, if you used to hate Brussels sprouts but now dig them? That’s not you becoming an adult. That’s your new taste buds being a lot less judgmental.

Bonus brain-wrinkler: The average tongue has 2,000–10,000 taste buds. And yes, they dull with age. So pour one out for Grandpa and his love of bland oatmeal.

2. Sloths Can Hold Their Breath Longer Than Dolphins

You read that right. Sloths, those slow-motion tree potatoes, can hold their breath for up to 40 minutes. Dolphins? About 10.

Here’s how: Sloths can slow their heart rate to a third of its normal pace when underwater, which reduces oxygen use.

Dolphins, though sleek and sexy swimmers, need to come up for air more frequently because they’re warm-blooded mammals with higher metabolisms.

3. There’s a Planet Where It Rains Liquid Glass—Sideways

Let me introduce you to HD 189733b, a planet 64 light years away where the skies are blue, the wind howls at 5,400 mph, and it rains molten glass... horizontally.

The blue color isn’t from a peaceful sky, it’s caused by silicate particles in the atmosphere scattering blue light.

Basically, this planet is every metal band’s album cover come to life. And proof the universe is both majestic and completely unhinged.

Final Word

You were today years old. Now tell someone else and sound smart over coffee. Or bourbon. Whatever works.
