Speaking of brains, my husband says he only has two brain cells left and those two are fighting each other.
I used to have an open mind, but my brains kept falling out.
We can most likely all agree that our brains are a precious part of us. According to a couple of websites I visited, the statement that we only use 10% of our brains is pure myth…bunk! Read about it at: https://faculty.washington.edu/chudler/tenper.html
That’s good news to me. I don’t like wasting things, especially my brain. Lately I’ve been thinking (using my brain!) that I should learn more about this marvelous thing, and maybe even do some things to keep those dendrites growing. Those are the things that make the synapses. I learned a long time ago that we can keep growing dendrites and that Albert Einstein’s brain was packed full of them. Apparently his brain was examined after his death.
We’d be lost without our brains. Look at all the things it does for us. I, for one, am going to look into things that can help me keep mine healthy. In the meantime, here is a list of 10 interesting things about the brain that I got from the internet.
- The average adult human brain weights approximately 3 pounds.
- The human brain is composed of approximately 75 percent water.
- The average weight of a newborn human infant brain is about 350 to 400 grams.
- Recent estimates suggest that the average adult brain contains approximately 86 billion neurons.
- Only about 10 percent of the brain is made up of neurons; the other 90 percent is mostly composed of glial cells. Glial cells perform a range of functions, including acting as a “glue” to hold neurons together. They also perform housekeeping functions by cleaning up excess neurotransmitters and supporting synaptic growth.
- The brain continues to form new connections between neurons throughout life. Old beliefs suggested that the brain was fairly set in stone early in life, but neuroscientists now know that the brain never stops changing.
- Among children and adults between the ages of 1 and 44, traumatic brain injury is the leading cause of disability and death.
- The most common causes of traumatic brain injury include falls, motor vehicles crashes, and assaults.
- The average size of the human brain has decreased by about 9 cubic inches over the past 5,000 years.
-
The brain uses a lot of energy. While it represents only about 2 percent of the body’s total weight, it requires about 20 percent of the body’s oxygen and 25 percent of the body’s glucose.

Okay, my brain is challenging your brain to keep up. Use it or lose it.
