A quick survey, by me, about birthdays and brains:

Closes no sooner than Monday 14th April 2025 at 12pm noon UK time.
It is a Google Form. It doesn't require you to sign in to Google or anything else, and it doesn't visibly store your email address, IP, or any other identifying information in the spreadsheet of responses.
Edit: You can see the number of people who have taken part updating in real time here: https://docs.google.com/spreadsheets/d/1C7VW40bBuob_itTv6cASoFINbXuhvfx4DnfPRksEmSs/edit
