The brain is like a muscle. When it is in use we feel very good. Understanding is joyous. — © Carl Sagan
The brain is like a muscle. When it is in use we feel very good. Understanding is joyous.
We are an intelligent species and the use of our intelligence quite properly gives us pleasure. In this respect the brain is like a muscle. When we think well, we feel good. Understanding is a kind of ecstasy.
Children love this idea that their brain is like a muscle that gets stronger as they use it.
Brain wave tests prove that when we use positive words, our "feel good" hormones flow. Positive self-talk releases endorphins and serotonin in our brain, which then flow throughout our body, making us feel good. These neurotransmitters stop flowing when we use negative words.
If you do not use a muscle or any part of the body, it tends to become atrophic. So is the case with the brain. The more you use it, the better it becomes.
Observation is like a muscle. It grows stronger with use and atrophies without use. Exercise your observation muscle and you will become a more powerful decoder of the world around you.
It turns out that this part of the brain is one of the first areas that's attacked by Alzheimer's disease. So we can now use some of the basic understanding of this part of the brain to ask the simple question, 'What is going wrong with these special cells in the hippocampus at the very earliest stages?'
Courage is very important. Like a muscle, it is strengthened by use.
Sexual intercourse... a joyous, joyous, joyous, joyous impaling of woman on man's sensual mast.
I don't like to plan. Very often, for me, acting is like loving; it's using the muscle that you use in loving, in that your heart feels open. Physically, you feel open. And so therefore your job is to enter, open, and listen. And see what happens.
On those days when I can spend a few hours getting some understanding, I feel fulfilled. I feel as if I have made good use of my time.
I feel like people often say I am not good at controlled shots or hitting it low, and I feel I'm very good at it, just don't need to use it as often.
I don't have confidence in my instincts, and I feel like I have to go through a very right-brain and left-brain process.
I'm honest with myself how I feel. If I feel good, I feel good. If I don't - if I'm tight - I don't just try to muscle through everything, because you've got to be a little bit smarter.
Gays don't have a lot of testosterone. I'm talking about that they use both sides of their brain. Straight men only use one side. Gay men are very bright, very handsome... they put themselves better together. They dress good, they decorate, they clean, they cook.
When I'm alcohol-free now and even to see the world around me, I appreciate it, but I never truly enjoy too much of it maybe because I feel like I'm a working musician. There are some joyous moments, but I will not think a joyous moment.
Because we do not understand the brain very well we are constantly tempted to use the latest technology as a model for trying to understand it. In my childhood we were always assured that the brain was a telephone switchboard...Sherrington, the great British neuroscientist, thought the brain worked like a telegraph system. Freud often compared the brain to hydraulic and electromagnetic systems. Leibniz compared it to a mill...At present, obviously, the metaphor is the digital computer.
