Serene of the Oakland Serenes

I'm fat, and I'm told I'm an "easy stick" for blood draws and injections. If they are looking after my comfort and safety, I can see a warning: "Warning: this may be uncomfortable and/or unsafe if you are very fat", but not a prohibition. My marrow is as healthy as anyone else's, and I'm healthier than either of my doctors (one of them said he would trade his bank balance for my cholesterol numbers). But I'm preaching to the choir, I know. Gah.
