All of the diseases you mentioned (and many more I'm sure) fall Into the category we call
"Opelitis". Be very careful as Opelitis is highly contagious and Opelitis has no known cure. In fact, many who thought themselves well rid of it find that it recurs many years later. Opelitis can be brought into remission for a short period oif time by the purchase of another Opel.
We are currently working on keeping our Opelitis at bay by repeating a mantra (not Manta) several times daily. Our mantra is "We have no more room, we have no more room....." So far it is working, but we are not sure how much longer we can hold out.
Welcome to the highly contagious disease ward!
