When I was a child I had an elderly lady as a neighbour, at every opportunity she would waylay my parents to tell them all about her latest health woes, and it got to a point where they would actively avoid her. They would have been the first to offer help if it was actually needed, but she just seemed to 'enjoy' her ill health whilst belittling her husband who was genuinely ill, and suffering from lung cancer. Having seen this it must have made quite an impression on me, as when I became disabled some 20 years ago I decided that the last thing I would do would be to constantly moan about my health, so instead I try to find things to do which give me something other than that to talk about, even though for the vast majority of time I am stuck in bed. I also try to keep in mind that there are ALWAYS people worse off than I am. This attitude leads people to say 'I don't know how you manage to keep so cheerful', so I guess the message here is that no one really wants to be dragged down by other people's health problems, we all have them, but to constantly witter on about it just pushes people away.
