Yeah, it's the story your brain tells itself about what those physical sensations actually mean.
Like, do you want what's coming or are you desperate to avoid it?
Think of your body as a high-performance car engine that just got slammed into high gear.
Oh, I like that.
The engine itself doesn't know if you're speeding toward a destination you absolutely love or if you're, you know, desperately fleeing a threat in the rearview mirror.
Right, it just knows it has to move.
Exactly, and it has to move fast.
It is raw, unadulterated horsepower just being unleashed into your system.
That engine analogy is exactly right.
And because the internal horsepower feels identical either way, the English language had to develop this incredibly distinct, highly nuanced vocabulary to separate the two.

It just has a biological job.
And its job is to prepare your physical body for immediate action.
It's the classic fight-or-flight response.
Which totally explains the physical symptoms.
Precisely.
Your heart rate violently accelerates to pump more oxygen to your muscles.
Your breathing becomes shallower and faster.
