I have always wondered how our brain knows time is passing. For instnace how does it know to pump the heart with a regular beat. I dont want to hear about synapses sending messages and the known events that occur. How does the mind know that time has passed?

This is a brilliant question. Most people regard time as some unseen force that causes us to go about our daily activities (such as going to work, eating, and sleeping). However time is a much more essential part of our beings than some third party motivator.

The original questions states that

, but the question can not be answered without calling upon our physiology. Let's take the female body as our first example. The menstrual cycle is the most obvious indicator that our body, the subconcious, has a feel for the passage of time. Femals menstruate with almost astonishing regularity. A few years ago I read a passage in a biology book while spending a couple of weeks in France. The book stated that our pre-homonid ancestors relied on the orbit of the moon to swim to the shallow waters of the temperate ocean and mate. As evolution took its course, modern day females still operate on this lunar calendar. As you know, our calendars are centered around the lunar orbit, thus tying together the natural cycle of our satellite and the fabricated calendar system.

There are many such examples of subconcious time awareness (such as circadian gene expression, sleep cycles, eating cycles, etc.), but they are all rooted in the combination of natural processes and our interpretation of time. This means that although is appears that our bodies are "watching the clock", they are actually just responding to various environmental alterations that act as a stimulus.

It's amazing how finely tuned our bodies are to inhabit this planet. I suppose that is what millions of years of evolution will do to ya Wink
