Many teenagers admire sports heroes and display their posters in bedrooms. However, there are concerns about whether these teenagers **emulate** the athletes' healthy examples. British parents worry that today's youth are not as fit and healthy as previous generations. **What** could be the reason for this? According to the British Heart Foundation, teenagers from 13 to 15 are **spending** a great amount of time watching TV or playing video games. A special report describes this generation **as** "couch potatoes" spending their time indoors, growing up in their bedrooms, relying on cars, and facing potential heart disease risks as they get older. Is this their fault? Are young people simply lazy? Many parents don't **let** their children play outside or walk to school alone because they think it is unsafe. Some teenagers blame their overprotective parents for their lack of fitness. Encouraging an active **lifestyle** and protecting their hearts is increasingly challenging for young people. Schools have also reduced the time **dedicated to** sports in recent years. Many students don't have time for sports due to exam preparations.
