Adrenaline
Last night I stayed on a parking place where caravans were prohibited. I was alone which gave me a bit of a weird feeling. Usually when I'm alone on a parking place I get fined.
In the morning when I lifted my head to look out the window, the first thing I saw was a car with the letters “G E N D A R M E R I E” written on it, driving towards the parking place. I immediately lied back down and my heart started racing. I tried to remain calm but I couldn't. This was adrenaline being most useless. Even if the police had stopped at my car, the additional physical strength and reaction speed would not have been useful to me. Luckily they just passed and so did my adrenaline rush.
Later today I was driving on a narrow country road with a sharp and deep edge. Leaving the road just a bit would have meant getting stuck and likely damaging the suspension and maybe even the main frame.
Not life-threatening for me but definitely life-threatening for my car. So when I got particularly close to the edge and realized the danger, without even thinking my left arm rapidly pulled the steering wheel towards the left and away from the edge.
This was adrenaline being most useful, probably saving my car's life. And it was interesting to observe once again how fast it acts. It gets secreted from the adrenal glands right above the kidneys and spreads from there rapidly, triggering an almost immediate reaction.
One piece of content that recently revived my interest in hormones was this two hour conversation between Andrew Huberman and Lewis Howes where they talk about all the essential hormones as well as related practices. Highly interesting! They're all related!
