Dad's been having some complications. The exact nature of the complications is not really relevant to the story. I'm more worried about him getting tangled up in the Medical/Industrial Complex. It seems like no matter how good of a medical care facility you go to, there's always the threat of this tipping point where the unintended consequences of the treatments you receive start to snowball and cause more problems than the number of problems that get solved.
I'm keeping my fingers crossed that he hasn't crossed such a line, but I'm getting the same nervous tic in the pit of my stomach that I sometimes get about the Netflix website when I see something hinky on one on the graphs or reports. Any given signal is innocuous all by itself, but everything goes up in flames before you know it.
I guess I should keep the travel websites handy.
