You can personalize the issue all you want. I feel for you, your father and your family. I don't know all the particulars of your father's situation, but did adequately insure himself. Cancer insurance is available, expensive, but available. I'm heavily insured, ad it is a priority of mine. I do without many things that most people would take for granted so that my family and I are sufficiently covered for most likelihoods.
First of all, thank you for the comment about my father. I shouldn't have personalized it, but it just gets to me sometimes. I just believe that healthcare should be given to all of our people, maybe it's a little unrealistic, but that's what I believe.
