I think this is a great idea and intend to join the fast. I also downloaded the book “The Murder of Nikolai Vavilov by Peter Pringle” that another commenter suggested - Vavilov deserves to be recognized! I have experience with fasting and generally find 36 hours very doable - especially helpful for longer fasts is having a clear sense of purpose which reinforces motivation and commemorating this great scientist in this way feels meaningful.
Great idea! I have marked my calendar.
