Just thought I'd share

One side of a conversation I just had in IM, after pointing out that 1) I donated blood today, and 2) I'm a little loopy:

Me: My arm is sore.

Me: Just noticed.

Me: Wow, I'm out of it.

Me: Perhaps it's the lack of oxygen-carrying elements travelling to my brain.

Me: I'm out of it and medically inclined.

Me: I'm a doctor in italics.
