Whenever we yawn, our larynx and pharynx expand which allows large volume of air to pass into our lungs which sends a wave of cool blood to the brain. This gives the brain a cooling effect which heightens attentiveness and makes us more alert.

The human brain works to its maximum when it is cool much like a computer. Such conditions as fatigue and stress cause our brain to heat up. That is why we find it hard to concentrate whenever we are stressed and even when sleep deprived. Although yawning appears to have a positive result on the human brain, there are still people who rarely yawn. They are the psychotics.

Life offers reasons or results. Some people get the idea that they both weigh the same. They don’t. If you’re not living the life you wish to live, doing the things you wish to do, no excuse will do. Look around. You can find all kinds of people beating the odds. We see men and women succeeding and experiencing happiness with the little education and even less money. These are achievers who point out that results are the only things that matter. They have made the same discovery as the man who said, “I used to blame the weather until I discovered it rains to rich people too!”

The enjoyment we derive from life is inversely proportional to how much we blame our circumstances.
