Walkin’ Pneumonia and The Boogie Woogie Blues

Three weeks and counting, this damn “Walking Pneumonia” (at least that’s what my doctor calls it) has had me in its grip. Five days go by, I feel terrible. Then I start to feel better for a couple of days, and back it comes for another five days, at which point I once again to begin to feel better, and then …
Of course the resolution to the illness is easy: for it not to have happened in the first place (antibiotics, which I’ve avoided for three weeks, commenced yesterday, so that’s a partial solution for the moment). And how might I have achieved this “not have happened at all” state of grace? Regular exercise (walking five miles a day, since I like to power walk), and maintenance of my South Beach diet, from which I slipped just before Christmas, and have yet to resume.
No secret this: a healthy diet and regular exercise = good health. When will I ever learn my lesson?
