About the need for a quiet room -- I totally agree with you. I wonder how many engineers talk about needing a door which can close for reasons like 'I need to focus' when the real reason is 'I have an anxiety disorder which is exasperated by chaos and eased by quiet.' I know I've said the first without mentioning the second.

In fact I turned down an offer purely because of an office plan which would put me between a Ping pong table and a room full of people (in an open office plan).
