Of course I don't have the ultimate answer, but... This idea of healthy (functional) and sick (dysfunctional) is as human as it is wrong. Being ill is just as justified as being healthy. It contributes to balance: to your inner balance, to the big picture... I don't wish anyone to feel unwell. But don't fight it; acceptance and patience are good counsellors. And by the way: yes, it is possible not to fall sick for 50 years or more. I've broken all sorts of bones, but I've never been ill.
