I agree. The truth is that @*#& happens and for some poor souls it happens in spades. I think we all have to be vigilant for any signs of disease (whatever it might be), do our best to stay healthy. If we choose to do the things that are said to put us at risk then we have to take it on the chin if we find ourselves with a diagnosis we aren't happy with. Being alive is the first risk factor and anything after that puts you in the crosswires.
I think the trick is to count our blessings and make the most of everything because there are no guarantees we will be in the line when they are next handed out!
