The optimal activity combination can change dramatically by adding one more activity to the mix.

In this age of constant evolution, it is imperative that we understand how humans’ bodies react to these changes in activity. This blog aims to do just this, and has been built on the assumption that we humans are complex adaptive systems. In this worldview, the system becomes an active participant in a system-wide process, changing as the system changes. The result is a system that is neither static nor dynamic, but rather a living organism that adapts to the changing environment, both in its internal workings and in terms of the external world.

Human behavior can be broadly broken down into four key areas; (1) Physical, (2) Cognitive, (3) Social, and (4) Psychological. We will review each of these categories, but first, we’ll look at some basics about living organisms. Physical life refers to the activity of living organisms, from the most primitive bacterium to the most sophisticated human being. It is important to note that physical life of an organism is not limited to its cells and their genes. Our biology has a strong emotional and psychological character. This is because we are the only animal class with a nervous system, and we have developed a sophisticated emotional system by developing more neurons. The result is a sophisticated psychological make-up. For our purposes, we will refer to this part of our biology as physical. Physical life is comprised of our genes, our nervous system, and our body. While it is technically possible to study the physical life of different species, it is also impossible to understand the full complexity of this life without understanding the psychological make-up of humans.

Cognitive life involves our abilities to think and reason. In evolutionary terms, this is a relatively new branch of the life of animals. It is here that we first developed thinking skills. Our ability to think allows us to solve problems as a result of our highly evolved brains. The process of solving these problems is commonly referred to as reasoning and is often the basis for our actions.
