The skeleton of an old woman has been found 7 years after her death, not in an isolated house in a small village. No, she was found in an apartment block in town. She died alone and isolated. Studies show that more and more people suffer from loneliness despite modern communication technology. Worst, the isolated people are most of the time those without access to the latest communication devices. This is true in France, it is even more the case in Germany where many choose to live alone. But the loneliest country in Europe is UK (http://www.theguardian.com/commentisfree/2014/jun/27/anyone-can-die-alone-isolated-age-uk-loneliest-country).
Family, colleagues, and friends are important for the social network that makes you feel that you are part of groups. How is it that up to 20% of the population claims to feel isolated in France? Some choose to stay away from their family. Some have difficulty in finding friends in a modern society where we are always busy, aren't we? I have learn that I have to make the first move to break the ice because many have prejudices when they see me like "You speak very well French for a Chinese.". In fact I am quite fluent in French! Living alone may be a choice. But loneliness is not.
