Oh my shoulders [teaching]

Overuse and overwork symptoms started showing up yesterday with a vengeance.

Need to keep my head down and keep plugging away at the to-do list.

There are fun moments. The video for this week's lab took extra time to record, but as a trade-off since some of it is Stupid Human Science, it is also entertaining (along with hopefully being at least somewhat educational).
