Interlude

I'm still here, just. Have been preparing to give a three hour talk tomorrow morning. Today was the first of two days of a workshop on AdS/CFT with just four speakers. I don't know what the first two said, as it was all Chinese to me. My talk 3(\pm 3) paths from AdS to QCD may or may not be pitched at a suitable level but whatever happens I'm sure to be exhausted afterwards. Will report when I've recovered.
