20．You may have been told before not to be afraid of anything．Fear is often associated with weakness．Fear is something to be avoided．
But that's not true，according to Time For Kids magazine．Fear can be good for us．
Fear tells us about danger．Without fear，we wouldn't know to run away from a tiger or step back from a cliff （悬崖）．
In a study published in the Justice Quarterly journal in August，researchers from Michigan State University said that a healthy fear of crime keeps teenagers away from potentially dangerous people，places，and activities．
Fear makes us jump，scream and sweat．But interestingly，sometimes we make ourselves feel fear on purpose．Think about scary（可怕的） books and movies，and also the long lines for a scary roller coaster ride．
Margee Kerr，a US sociologist，explained why to Time For Kids．
Fear fills our brain with healthy chemical substances （化学物质），especially endorphins （内啡肽） and dopamine （多巴胺），and these things create feelings of happiness and excite us，according to Kerr．
In addition，when you're scared，your body produces a chemical which helps people bond with  each other．
"Watch people walking out of a haunted house，and you'll see lots of smiles and high fives，"Kerr told Time For Kids．That also explains why schools and companies organize challenging trips and physical activities to build up team spirit．
People experience and deal with fear in different ways．If you happen to be a"coward"who gets scared easily，don't worry．There is some evidence that being scared can help a person manage stressful situations．
Kerr said that things like giving a report in front of your class or performing in a school play help build a sort of endurance （忍耐力） to fear that makes us more confident．
"You become more comfortable with the physical experience of fear，and so you're better able to work through it during tense situations，"said Kerr．
So learn to love your fear．It only grows when we forget how helpful our fear is trying to be．
