Yoma 81: The Afflictions of Yom Kippur Are a Positive Thing

Can one measure that would violate Yom Kippur be combined from food and drink? The claim is no, and that is not disputed, apparently. R. Yehoshua says that if two different items are identical in volume and also in the type of impurity, they can combine for the sake of impurity - but only if both factors of sameness are in place. Also, the new mishnah. If one forgot it was Yom Kippur, and both ate and drank in that period of forgetting, then only one Korban need be brought. Which leads to a discussion of affliction, and how it is a positive commandment for the day of Yom Kippur. Plus, if you ingest edibles that aren't food, you're not obligated for the violation on Yom Kippur. For example: pepper, ginger.
