Which is the most difficult to be : a child, a teenager, a middle-aged or an elderly person ? Every age has pluses and minuses. In my opinion it is the most difficult to be an elderly person.
The first argument is feeling lonely. When we are old, nobody has time for us. Children work and rarely visit their parents, because they have other duties.
Grandsons have a thousand of other classes than the visit for the ailing grandmother. (chodziło mi właśnie o zajęcia w szkole, obowiązki szkolne. A co do czasownika odwiedzać to chyba visit jest odpowiedni?) It is harder for an elderly person to make new friends. They sit and wait at home until somebody visits them...
Health problems are another argument. An elderly people are susceptible to illnesses.
It results mainly from the age. The going to the shop, or working in the garden is a big effort. It is hard to move because they have aching bones.
I think that older persons have also a problem with finding their place in today`s difficult world. Technology often weighs down on them. Today we can`t live without the computer and smartphones. For them it is something definitely new and strange. Most of them have no money because have low pension.
Being an elderly person is a fight for survival but there are also positive aspects. An elderly person has a lot of free time ! They can travel and pursure their hobbies. They can sleep to 2 p.m ,don`t think about learning and work.
I think that being elderly person is difficult. Everyone wants to be young and fit as long as possible. Some persons have really heavy life. They don`t have help from family and friends. They must spend their old age in solitude and die in pain and suffering. It is very unpleasant.
