Please pardon if OT. I'll try to highlight the relevant parts:
Brain chemistry reveals an essential unity of mind and body. Neurons not only contact other neurons, they also connect with skeletal muscles, at a specialized structure called the neuromuscular junction. There the brain uses acetylcholine – its primary chemical neurotransmitter for memory and attention – to communicate with muscles. Another of the brain's key chemical messengers, dopamine, helps regulate fine motor movement.
The role of these neurotransmitters in regulating movement underscores the intimate relation between body and mind, muscle and memory. In fact, many bodyworkers find that deep massage can trigger the release and awareness of powerful, long-held emotional memories.
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.)
Try to include one or more of your senses in an everyday task:4
Get dressed with your eyes closed
Wash your hair with your eyes closed
Share a meal and use only visual cues to communicate. No talking.
Combine two senses:
Listen to music and smell flowers
Listen to the rain and tap your fingers
Watch clouds and play with modeling clay at the same time
Go to work on a new route
Eat with your opposite hand
Shop at new grocery store
These are some tips to avoid many brain damages later in life-
Research on the physical results of thinking has shown that just using the brain actually increases the number of dendritic branches that interconnect brain cells. The more we think, the better our brains function – regardless of age.
Walking Benefits Brains
Walking is especially good for your brain, because it increases blood circulation and the oxygen and glucose that reach your brain. Walking is not strenuous, so your leg muscles don't take up extra oxygen and glucose like they do during other forms of exercise. As you walk, you effectively oxygenate your brain. Maybe this is why walking can "clear your head" and help you to think better.
In the morning, while you're still in bed, slowly begin to move your toes – any way that feels good. Wriggle, scrunch, and stretch. Move all your toes up and down several times, or work just your big toes. Wiggling your toes activates nerves that stimulate your brain and internal organs.
Do this exercise first thing each morning or after sitting for an extended period of time. It will help you to wake-up and become alert more quickly. Your whole body may feel pleasantly energized. Most important, your first steps – and those throughout the day – will be safer ones. (Falls are the second leading cause of spinal cord and brain injury among people over 65 years old
The human foot is one of the body's most complex engineering marvels. The eight arches in your feet do a remarkable job of evenly distributing the weight of your body, while 200 ligaments coordinate 40 different muscles that control the 56 bones in your feet – one fourth of all the bones in your body!
So who walked more, Agrarians or the invading Nomads (& their immediate ancestors)?
