Let's look more closely at this mechanism. Inside your body are two pedals belonging to the "autonomic nervous system": the accelerator (sympathetic nervous system) and the brake (parasympathetic nervous system). In your case, the accelerator is set to press harder from birth.
You can see this in your "HRV (heart rate variability)"—the fluctuation in the intervals between heartbeats. When the sympathetic system dominates, the rhythm becomes uniform; when the parasympathetic system dominates, it fluctuates healthily. Because you lean sympathetic-dominant, emotional waves translate directly into physical responses. That pounding heart when you're excited? That's this mechanism at work.
There's also a mechanism behind your morning energy. The "cortisol awakening response (CAR)" is a phenomenon where the stress hormone cortisol peaks about 30 minutes after you wake up. Your response is large, which is why you can hit the ground running. But think of it as "borrowing energy from the morning"—the tank runs low by evening. Once you understand your physiology, you can plan deliberate recharge breaks in the afternoon and make your energy last all day.
