A Snap shot of me at work.  I look like a bit of a twit really.   a medical version of a great Australian inventor/bushranger.   I was being fitted for a Duckbill mask,  to keep me safe from airborne viruses such as swine flu or bird flu.   The process involves initial testing where you  are sprayed with a bitter aerosol just to chk that you can taste it.  This only takes a minute or two.    About an hour later  the testing resumes with a duckbill mask on.   The second session  takes about 7 minutes,  in which you are sprayed with bitter aerosol and asked to breath through your mouth and move you head as directed.   I must admit I did not really enjoy this,   the Perspex fogged up rapidly, and despite the open top,  it kind of felt like you had placed a plastic bag over your head.   This fitting and test is an annual event.    I look forward to next year.
