Danny //.I may be wrong but I think that loneliness is more prevalent amongst women.//
My experience doesn't show that at all- and particularly since women are more likely to be widowed than men.
They do seem to have better support systems with friends and relatives and also, are generally, more independent. It sounds sexist perhaps, but as far as I see, it is often the wives who have cooked, cleaned and looked after others and their general outlook seems more turned towards others.
That may change over time, as society is... but that is more my experience over the last 20 plus years. Men seem more 'lost' without their wives. And statistics do bear it out, that women do better single, while men are less happy and healthy.
