The health of the sick is a loosely translated title of a favorite short story by Julio Cortázar, "La salud de los enfermos", and that pretty much sums up where I've been lately.
In spite of considering myself rather healthy, every once in a while I fall with a severe case of something I hadn't had before. In the past decade I experienced the charms of allergic rinitis (once I counted 100 sneezes in one hour!!!), kidney infection (nasty), cytomegalovirus infection (with a week watching cable TV in a hospital bed) and right now, bronchospasm.
I'd say that only the kidney infection was painful. But it was, and the others as well, rather interesting experiences. They are undoubtedly uncomfortable and they take me out of my daily drill, but they make me marvel of how good everything normally goes. Of how wonderful it is to be able to smell perfume without sneezing violently (not to mention to appreciate it, that's heavenly!), of making a visit to the toilet quick and uneventful, of doing my daily walking and climbing stairs without being left gasping for air (or feeling a little woozy after a coughing fit), and after the CMV wild ride, of how incredibly good it is to be able to hold my head higher than the rest of my body.
They say you don't appreciate something until you lose it, but I don't think it needs to be so. Having it temporarily taken away from you does help, though. Helps a lot.
