Interesting article.

I particularly like how you do not try to get too specific about the chemistry behind some of the biorhythms that occur for us during the course of the day and exactly how and why they work.

The human body is one of the most complex things Nature has ever created. We, in our arrogance, think we know most of the reasons why something happens to us or how our body works.

When we get to a point where we can manufacture a Lamborghini that repairs itself reliably when it is faulty, or are able to reliably predict the weather a month out, maybe we can start thinking about writing the comprehensive treatise on the functioning and creation of all things human.

Certain neurotransmitters tend to produce certain actions in the body and the brain, for sure, but their interaction with all the others and every other thing our bodies do, is another thing.

I get a kick out of scientists who say things like: “We know a lot about the beginning of the universe down to the 100,00th of a second from the Big Bang, but understanding what happened a millionth of a second after the explosion is more tricky.”

So your calling a neurotransmitter “drowsiness” is a way of describing something biological without the hubris of suggesting that you know exactly what is going on.

The description is good enough to suggest why we may want to modify our habits and routines to produce a better result in our day in general and in our mornings, in particular.
