Summarising a text involves answering the question: Whatkeyideas does the writerwant to communicate? A summary does not have to be long and should not includetoo much detail.
T ext 4b well connected? The biological implications of ”social networking"
One of the most pronounced changes in the daily habits of British citizens is a reduction in tf}e number of minutes per day that they interact with another human being. Recent history has seen people in marked retreat from one another as Britain moves from a culture of greater common experience to a society of more isolated experience. She is in good company, as Americans too step back from one another in unprecedented magnitude.

Social scientists reportde in 2006 that fewer than two decades "the number of people saying there is no one with whom they discuss important matters nearly tripled”.The number of both kin and non-kin confidants is described as "dramlatically smaller”(McPherson，Smith-Loven, ＆Brashears, 2006). A 2003 report by the UK's Office for National Statistics (Ruston, 2003)found that Britons now spent approximately 50 minutes a day interacting socially with other people. Couples now spend less time in one another's company and more time at work, commuting, or in the same house but in separate rooms using different electronic media devices. Parents spend less time with their children than they did only a decade ago. Britain has the lowest proportion of chil山en in all of Europe who eat with their parents at the taL}le. The proportion of people who work on their own at home continues to rise. The report went on to say that in the 20 years to 2003, "the proportion of people living alone doubled:- a trend highly pronounced in the 25- 44 age group. For the first time in our history a third of the adults in this country live alone, a trend that looks set to continue.
Figure 1. The amount of face-to-face social interaction declines as use of electronic media increases. These trends are predicted to increase (data abstracted from a series of time-use and
demographic studies).
Britain's disinclination for togetherness is only ecjua1led by her veneration of comm unicating through new technologies. The rapid proliferation of electronic media is now m aking private space available in

are physically and socially disengaged from the people around them because they are wearing earphones, talking or texting on a mobile telephone, or using a laptop or Blackberry. US Senator Carl Kruger described how people walking around "tuned in" were, in the process of being tuned in, being "tuned out" to the world around them. The malady is referred to as "iPod oblivio n".
Eye and ear contact
C1lildren now spend more time in the family alone in front of TV/computer screens than doing anything else (Sibman, 2007). A 2008 study (Childwise, 2008) reports that25% of Gritish five-year-olds oen computer or laptop of their own. In particular, the study noted an enormouts increase in "social networrking" among younger children which had overtaken fun (online games) as the main reason to use the Internet. Time that was previously spent interacting socially has increasingly been displaced by the virtual variety. A 2008 editorial in the .l ourna} o f the Roycel Socie。)o f Medicine (Abbasi，2008) made the timely point that social networking”encourages us to ignore the social networks that form in o
ur non-virtual communities”,and argued that”the time we spend socialising electronically separates us from our physical networks”. But why precisely should physicians be concerned about these changes in people’s actual contact and interaction with one another? One reason is that social connection is increasingly associated with physiological changes known to influnce both morbidity (the incidence of disease in the population) and mortality (the death rate).
Morbidity
According to the Oxford English Dictionary morbidity refers to”the rate of disease, or a specific disease，in a population”. Several decades of research have found that greater social contact is related to reduced morbidity while fewe:contacts lead to increased morbidity. This relationship is valid independent of the individual’s earlier health status.
Rutledge et al. (2008) reported that women with fewer social relationships experienced strokes at more than twice the rate of those with more social relationships after adjusting for other possible medical reasons for strokes,A further study on strokes, involving experiments on male and female mice，reported that social interaction reduced concentrations of a protein linkeu with strokes, and decreased theamount of damage to body tissue caused by the inflow of blood during a stroke.
Loneliness is found to be a unique predictor of age-related differences in blood pressure when the heart is pumping blood. And blood pressure for married adults-especially those happily married-declines more during sleep than for single people who may therefore be at much greater risk of problems with the heart and blood vessels，In one experiment, in which men were challenged in order to increase their blood pressure，it was found that blood pressure returned to baseline levels more quickly in the men with more close friends.
The incidence of senile dementia (Alzheimer's disease)-serious mental disorder in older people-is expected to double within a generation，and research conducted by Harvard University’s School of Public Health(Ertel et al., 2008) examined the influence of social integration, including frequency of social interaction, on changes in memory in 16,63 8 subjects aged 50 and older. The study concluded that the rate of memory loss among the least-integrated was twice the rate of loss among the most-integrated. Others report that the frequency of social interaction is inversely related to the incidence of dementia and may protect against dementia.
A positive relationship between the sheer amount of regular actual social contact and cognitive functioning has,however, been found in a variety of age groups including
younger adults. Most interesting is the study byYbarra et al. (2008) in which participants who interacted socially for. only 10 minutes Showed improved cognitive performance, performance equivalent to that displayed by partcipants engaged in so-called intellectual activities, The authors believe the results show not only that the effect is causal but also that the process is very sensitive to only small amounts of social interaction. They conclude: "Social interaction directly affects memory and mental performance in a positive way.”
Marriage and cohabitation
Ruston(2003)reports that the long-recognised protective effect of marriage against suicide has persisted over the past 25 years，despite changes in marriage patterns. Between 1983 and 2004，suicide rates for single people were around three times higher than for married people. For single women，the differential compared with married women widened from just over two times to three times.Unfortunately, our marriage rate is at an all-time low.
Statistics indicate that the protective effects conferred by marriage are cumulative, as are the harmful effects of years being divorced (Lund et al., 2006).
Conclusioneditorial英文
while the precise mechanisms underlying the association between social connection, morbidity and mortality continue to be investigated，it is clear that this is a growing public health issue for all industrialised countries.Kraut et a,(1998),a detailed classic study of 73 families who used the Internet for communication (the”Internet paradox" study)，concluded that greater use of the Internet was associated with declines in communication between family members In the household，declines in the size of their social circle, and increases in their levels of depression and loneliness. The study went on to report "both social disengagement and worsening and limited face-to-face poor quality of life and diminished physical and psychological health".
Children are now experiencing less social interaction and have fewer social connections during key stages of their Physiological,emotional and social development. An increasing proportion of men and women are living alone during Their”mating years”,having far fewer social contacts，And as the greying of the population continues，the incidence and effects of social isolation become ever more pronounced，Biologists can play a pivotal role in addressing these issues，By making the abstract concept of social connection and its effects more concrete and measurable，biology may finally provide the key to public awareness.Pres id ing over a
