To function well

 The cold weather has arrived and we've already been using boilers, stoves, and fireplaces for some time.

Heating systems require two things: fuel and air. If one or the other is missing, the system will not start, shut down, or malfunction.

The same thing goes for us, we need food and water, but even more so air. 

Now, mind you, we have plenty of food and water, but what about air?

We live in constant tension, plagued by anxieties, fears, and needs. Or we're focused on our smartphone screens.
The result?
We live with tense bodies and malfunction, which is why most ailments today are psychosomatic in nature.

Do you want to function?
If your answer is yes, the first thing you need to do, like with a stove, is ensure good airflow.

If you function, everything works; if you don't function, nothing works.
