What You Breathe

“Don’t stop breathing!”

A: “Do you know how to live a long life?”
B: “Tell me.”
A: “Don’t stop breathing.”

It’s meant to be a joke. But no joke.

Since we have to breathe almost every second, why not breathe a better quality air?

We can’t spend our whole life living next to a waterfall in order to have the best quality air. But now, thanks to the advancement in technology, we can be in a room studying, working or resting, with air that is full of negative ion.
