I hope everything works out for the best. I just had a couple bad blood clots in my legs and lungs this past couple weeks which is why I have not been around. Ironically they are most likely from sitting wrong and spending way to much time on the net. It was a real wake up call to get some more exercise and start eating better. I hope that this is how it works for your Dad. Just scary enough so he starts taking better care of himself and is around for a long time. I much prefer it to be myself in distress rather than a family member because it is much less frightening. I (and most people) can handle the idea of our own deaths much better than that of a loved one. My biggest worry was that I would be a burden to my family.
