Jmh I agree with most of what you say except with the claim that it’s the amount of time spent learning that determines whether one deserves to learn in kollel. There are some that need the coffee/cigarette breaks like you and I need air to breathe and water to drink. So yeah they take breaks but these people are allowing the Torah to penetrate their souls and could not live without learning Torah all day. These people, after a day of learning are on fire and really managed to change the world with their learning. Not everyone who is in kollel is meant to be there but just because someone can’t sit still for as long as you’d like doesn’t give anyone the right to judge how much their learning means to Hashem.
