Three cool bags and a thermometer

Two lines a day in a paper diary. Date, and one thing. That is the entire system and it has twice changed a clinical decision.

Tested three cool bags against a thermometer this weekend because I am that person. Results written up for the travel circle.

Batch cooked on a good day for the bad days. Six labelled boxes in the freezer and a great deal of smugness.

To be revisited.
