Look JoeBro, I'm sure your wife is a fine and lovely person, although deranged as she married you, and is quite serious about her work, but I'll go with the CDC.
Shingles is nasty to say the least and I don't need that in addition to a the other little problems I have. I got a shot about 5 years ago with no ill effects. Although I'm so fucked up I wouldn't notice a side effect.....LOL......All kidding aside, GET THE FRIGGIN' SHOT!!!
