As a child, I was really afraid of the dark and of getting lost. These fears were very real and caused me some uncomfortable moments. Maybe it was the strange way things looked and sounded in my own room at night that scared me so much. There was never complete darkness, but always a streetlight or passing car lights, which made clothes on the back of a chair take on the shape of a wild animal. Out of the corner of my eye, I saw the curtains seem to move when there was no wind. A very low sound in the floor would seem a hundred times louder than in the day. My imagination would run wild, and my heart would beat fast. I would lie very still so that the "enemy" would not discover me.
Another of my childhood fears was that I would get lost, especially on the way home from school. Every morning I got on the school bus right near my home. That was no problem. After school, though, when all the buses were lined up along the street, I was afraid that I would get in the wrong one and be taken to some other strange places. On school or family trips to a park or a museum, I wouldn't let the leaders out of my sight.
Perhaps one of the worst fears of all I had as a child was that of not being liked or accepted by others. Being popular was so important to me then, and the fear of not being liked was a serious one.
One of the processes growing up is being able to realize and overcome our fears. Understanding the things that scared us as children helps us achieve greater success later in life.
Certain activities can be good or bad for our brains, so let's see which of the seven habits you should carry on doing or give up.
Sitting still When we sit for long periods (more than three hours), our inactivity decreases the blood flow to the brain and the oxygen supply. This decreases brain activity in the part of the brain we use for thinking, organizing and decision-making. Action: Relax the brain by getting up to stretch and move around every 30 minutes. |
Staying curious Learning new skills leads to better understanding - the brain's ability to form new connections between existing neurons(神经元). Action: Why not take up a musical instrument or an evening class? |
Fast food The quickest way to jam our brains is to fill our bodies with fast food. Too much salt leads to more brain illnesses. Action: Eat fresh and green food as much as you can. |
High-quality sleep Studies have shown being deprived(剥夺)of sleep for 24 hour decreases memory and concentration. But regular, restful sleep improves memory. Action: Try and go to bed before midnight and aim for 7-8 hours' sleep. |
Being overweight Obesity does great harm to the brain and is also a risk factor for cognitive(认知的)decline. Action; Try to lose some weight if you are too fat |
Drinking alcohol regularly Regular drinking lowers the levels of serotonin (血清素) in your brain and can make you depressed. Action: Many medical experts recommend taking regular days off from drinking to ensure you don't feel sad and don't become addicted. |
