it is not so much the amount of blood that is the problem but that the heart is used to pump against a given flow resistance and that resistance changes with the number of reduced "consumers". It is a little like with the electrical grid, when large consumers suddenly go offline/online, the power plants have to adjust their generation to not cause a systemic failure.
I tested ChatGPT's insights into history, politics, medicine, culture. Given it has a cutoff date in 2021 it cannot know any events thereafter or know the difference between fact and fiction. (ChatGPT-4 is supposed to be online).
ChatGPT has permanently a bias for what can be considered mainstream perception of things. It is aware of alternative views, arguments and likes to remind the reader permanently that these views are not generally shared.
