My ear hurts

So, as things are a bit wet, I couldn't go out to Surrey to meet those customers today. Fortunately, in this wonderous world of technology, there was an alternative, and so we've done the whole thing via conference call and Live Meeting instead, which is great.

However, my specialty in this particular scenario turns out to be rather unwanted, and so I've been on the phone for over 4 hours so far today, and I'm fairly sure my sentences per minute are somewhere around the 0.1 mark. I'm sure this can't be healthy for me, mentally if not physically.
