Five friggin' hours in a not-totally-comfortable office chair today in the Zoom meeting mentioned previously. My very well-padded but is feeling the hurt/numbness from those two sessions, with a one hour break for lunch.
Normally at the physical meetings I lead two 50-minute sessions between 9am & 10:50am. Today I did those plus 30 minutes before & after fine-tuning the show.
Then after lunch I took on another 50-minute session 'cos the regular presenter was away.
So I have a big dose of butt-hurt.
