If I'm generally fit and healthy and getting good sleep I tend not to get ill - I only get colds and things if I'm stressed, run down and tired so to be honest I do sometimes take to my bed, more because my body's telling me to take break! I've learn't the hard way that if I carry on my colds, although rare, if not cossetted tend to go into bronchitis, pleurisy or pneumonia so I take the hint!
If I had a serious illness I'd like to think that I'd cope well but I have a tendency to want to cope alone and that always cause friction with Mr Hellion who thinks I'm too self sufficient and that drives him nuts.
