An interesting study posted on Facebook recently shows how men and women develop new interests as they mature (成熟) . While women tend to take exercise seriously from the age of 34 , men will wait until their 45th birthdays before working hard to get in shape . The average woman spends more time talking about sports , politics , career and money as she gets older . Women's interest in books reaches its peak (顶峰) at the age of 22 , while that of men does so when they are in their 50s . Men start to change their focus from the workplace to other things after age 30 , while women do not do so until eight years later . Both , however , care most about fashion at age 16 . The research used anonymous (匿名的) data donated by thousands of Facebook users , recording the statuses , ‘likes' and‘interests' they had posted on their profiles . It found the average woman talks about television most at 44 , while men peak much younger , at age 31 . Men are also most likely to see a film in a cinema at age 31 , while women go out to see films most when they are only 19 . Men are most interested in travel at 29 , women at 27 , while women talk most about food and drink at 35 , and men at 38 . And if you are middle aged , a safe topic for any audience is the weather , which is a key interest for many as they approach 60 . Stephen Wolfram , the British scientist who carried out the research , says , "It's almost shocking how much this tells us about the changes of people's typical interests . "People talk less about video games as they get older , and more about politics . "
