【正确答案】Generally speaking, our grandparents' generations were physically fitter than today's population. There are several reasons for this and also a number of strategies which could address the issue. First of all, previous generations were more likely to have worked closely with the land and in farming industries, which improved their physical fitness and strength. They also probably walked to places a lot more as cars and transport were not as common. In addition, there were also not the electronic, sedentary distractions of today, such as computers, televisions and playstation games. Our grandparents would more commonly have played outside or played sports than stayed indoors playing computer games and this has contributed towards a lack of fitness in today's generation. Finally, their diet was much healthier and based around fresh fruit and vegetables, in contrast to the fast food many people consume nowadays. Possible measures which could be taken to address the problem of this lack of fitness include more focus on physical activity, especially for children. Government awareness campaigns which provide information about the target level of physical activity each day and how to achieve it assist individuals to get moving. Furthermore, families can make exercise fun by doing it together or encouraging their children to play sport and play outdoors. Schools and universities can also promote physical activity through the curriculum and sports clubs and events. All in all, although today's generation is less fit than previous ones, there has been a shift in awareness to address this, which will in turn hopefully break the pattern of inactivity and poor fitness for future generations.
