I agree with Del (gods help me!), but I can very much understand what Tony is feeling.
A mate of mine was born with Brittle Bone Disease. He and his wife had a son, and thankfully, he didn't have it.
However, they used to babysit for his nephew who had inherited the disease. One day, the kid fell off the sofa - only 6 inches from sofa to carpeted floor, but something went phut.
They took him to A&E (or ER for the Americans amongst us!) but although they explained to them what the kid's condition was, they ended up with cops and social services arriving as the hospital thought the kid had been abused.
All sorted in the end, but Bill was very wary of looking after the kid after that.
Great story - not.
Bill slipped one winter, and broke his leg. He knew it was broken, coz he'd had so many breaks before.
In the hospital he explained, and, long story short, he ended up lying on a bed with a consultant and a load of junior doctors around his bed. He explained that one of the things that makes it obvious about brittle bones was the fact that the whites of the eyes are more a silvery/grey colour.
One med student asked him "Is it as painful when you break a bone as it is with normal bones?"
Bill's response? How the F*** would I know?
Some are born great, some achieve greatness and some have greatness thrust upon them.
The rest of us are a bit crap.
