What R’ Aharon Kotler Did When He Was Unwell

Rav Aharon Kotler and Rav Ruderman once met. Rav Ruderman mentioned he had skipped his shiur because he was not feeling well. Rav Aharon replied that he does the opposite — when unwell, giving the shiur is what makes him feel better. Rav Ruderman smiled: “If I were as confident in my shiur as you are in yours, the same would be true for me.”
