※ 引述《nukchichi (haha)》之銘言: : 105.The following appeared in a health newsletter. : "According to a recent study, people with many social ties report catching : colds less often than do people with few social ties. Consequently, : researchers conclude that having an active social life probably helps : strengthen the immune system. The researchers note that catching a cold-one : of a family of highly contagious viruses-gives the cold-sufferer temporary : immunity to that virus in the future, but not to the many other related : viruses. Merely being exposed to a new cold virus, however, is not enough for : a person to catch a cold, since a strong immune system can successfully fight : off some new viruses. Thus, in order to prevent catching a cold, people : should strengthen their immune systems by becoming more active socially." : 我想請問 大家對這題要怎麼反駁?? 我想了兩三天...它是有點怪啦~但就是不知道 : 把那個"怪"找出來~ 我只想的出來 第一、倒因為果,事實是因為感冒了才不會去社交 不是因為有社交才沒有感冒 後面想不出來... -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 61.229.127.174
