Since we are social beings, the quality of our lives depends in large measure on our interpersonal relationships .One strength of the human condition is our possibility to give and receive support from one another under stressful conditions .Social support makes up of the exchange of resources among people based on their interpersonal ties .Those of us with strong support systems appear better able to cope with major life changes and daily hassles(困難). People with strong social ties live longer and have better health than those without such ties. Studies over types of illnesses, from depression to heart disease, show that the presence of social support helps people fend off(擋開) illness, and the absence of such support makes poor health more likely.

           Social support cushions stress in a number of ways .First, friends, relatives and co-workers may let us know that they value us .Our self-respect is strengthened when we feel accepted by others in spite of our faults and difficulties. Second, other people often provide us with informational support .They help us to define and understand our problems and find solutions to them. Third, we typically find social companionship supportive. Taking part in free-time activities with others helps us to meet our social needs while at the same time distracting (轉移注意力)us from our worries and troubles.

Annealing

Annealing is a way of making metal softer by heating it and then letting it cool very slowly, if metal is heated and then cooled very quickly, for example by dipping(浸) it in water, it will be very hard but also very brittle(脆)—that is, it will break easily. Metal that has been annealed is soft but does not breaks as easily. It is possible to make metal as hard or as soft as is wished, by annealing it. The metal is heated, and allowed to cool slowly for a certain length of time. The longer the heated metal takes to cool slowly, the softer it becomes. Annealing can also be used on other material, such as glass.
