Here is the promised Anki deck for "Some key numbers that (almost) every EA should know".
Due to time constraints, we were not able to include all of the numbers suggested in the original thread. These may be added in a future version. Please go to the deck's GitHub repository for details on how to be notified when new versions are released.
Please report problems, or leave suggestions, below.
(Note: If you don't use Anki, you can access the deck's contents here.)
The content of those cards also represented the biggest update for me. I wouldn't have guessed that the truth was roughly "two third of neurons are invertebrate neurons, one third of neurons are fish neurons".
