1. Walking pneumonia is really not a big deal any more. I’ve had it maybe 10 times; it is very annoying indeed, but, normally, like HRC, I have not bothered telling anyone about it. Indeed, whereas she apparently told close friends and family, I sometimes don’t bother (its not as though anyone is going to have any sympathy—“Go get antibiotics and steroids, now, you idiot”).  Her failure to tell the world she has a minor ailment is not part of a pattern of secrecy.
2. Or maybe she doesn’t even have the ailment. Could it be that there is nothing wrong with her, and this is just a rumour spread by her campaign i) to make her seem a bit more like a normal person and ii) to panic people (like the Bushes, for example) who think they can sit this out without having to take responsibility for the deranged performance artist becoming President, and move them into positive action?
 A tip—Since I started getting a regular 8 hours sleep the colds that previously would turn into pneumonia occur about 1/4 as often, and last about half as long. Another tip: avoid children.
 with apologies to the excellent senior Mrs Bush, who has made it clear that she is not going to stand by.
