I will discuss ideas around symmetry and Wick rotation contained in joint work with Mike Hopkins ( This includes general symmetry types for relativistic field
theories and their Wick rotation.  I will then indicate how thebasic CRT theorem works for general symmetry types, focusing on the case of the pin groups.  In particular, I expand on a subtlety first flagged by Greaves-Thomas.
