Sam2 – yekke: Similarly, you need to prove that doing that affects one’s learning. I thought it was an explicit Gemara that the opposite is true. Learning removes those tendencies.
I am not going to fight with YOU about that, if you can’t find a mekor I certainly won’t be able to! I think I heard it besheim Rabbeinu Yona, but don’t remember offhand. Will try find the mekoir!
