Stress is your body’s response to demands that are placed on it.It’s the “wear and tear” experience as you continually make adjustments to changes in your life.Demands may be external, say bills, friends, work, relationships, or they may be in your mind, for example, how you feel about yourself.So stress is commonly considered to be a bad thing.Is it really the case?Not really.In fact, I should say, everyone needs a certain amount of stress in order to live well.Stress is what gets you out of bed in the morning, giving you extra zest and vitality to do all sorts of things: presentation, sport, work.But too much stress may cause problems.

　　压力是对你所施加的需求的身体反应。这是随着你不断调整你生活中的改变的“磨损”经验。需求肯能是来源于外界，如法案，朋友，工作，关系;也可能是存在于你脑海中，比如你的自我感觉。所以，压力是普遍被认为是一件坏事。事情真的是这样吗?不是的。事实上，我们应该说，为了生活得更好，每个人都需要一定的压力。压力每天早上把你从床上拉出来，给你额外的热情和活力去做各种各样的事情，如演示，运动，工作等等。但是压力过大可能会引起问题。
