Plasticity is the basic mental drive that networks your brain, giving you cognition and memory – fluidity, versatility, and adaptability.

Before birth you created neurons, the brain cells that communicate with each other, at the rate of 15 million per hour! When you emerged into the world, your 100 billion neurons were primed to organize themselves in response to your new environment – no matter the culture, climate, language, or lifestyle.

A healthy, well-functioning neuron can be directly linked to tens of thousands of other neurons,

A healthy, well-functioning neuron can be directly linked to tens of thousands of other neurons, creating a totality of more than a hundred trillion connections – each capable of performing 200 calculations per second!

Many neuroscientists believe that learning and memory involve changes at neuron-to-neuron synapses.

Travel is another good way to stimulate your brain. It worked for our ancestors, the early Homo sapiens. Their nomadic lifestyle provided a tremendous stimulation for their brains that led to the development of superior tools and survival skills. In comparison, the now-extinct Neanderthal was a species that for thousands of years apparently did not venture too far from their homes. (Maybe they were simply content with their lives – in contrast to the seldom-satisfied sapien.)

Exercise is a natural part of life, although these days we have to consciously include it in our daily routine. Biologically, it was part of survival, in the form of hunting and gathering or raising livestock and growing food. Historically, it was built into daily life, as regular hours of physical work or soldiering. What is now considered a form of exercise – walking –was originally a form of transportation.
