In my opinion, I think old people should live in the country because they can enjoy their life comfortably.
First, living in the country is more peaceful and quieter. There is not much traffic there and old people don't suffer the noise from vehicles or factories,...
Secondly, in the countryside, old people can have a healthier life than that in the city. They can breathe in fresh air which is good for them because there is less pollution. Moreover. they also approach the natural scene such as the sunrise or sunset, the streams, or lake... In the afternoon, they can walk along roads as go sightseeing and also do exercises
Thirdly, living in the countryside is safer and cheaper than that in the urban areas. Last but not least, they can make new friends. The people in the countryside is not only friendly but they also are hospitable. Old people will be more optimistic and happier when living in the country.
In conclusion, I think living in the country is a good choice for old people. It is suitable to rest and relax
