Question
According to Halacha, is Brain death in animals considered death for the purposes of "Ever Min hachai"? So could a brain dead animal have its limb removed and eaten for Noahides? Obviously Jews have to have shechita but since non Jews don’t is brain death enough for it to be kosher for them?

Question
Shalom aleichem Rabbi Lauffer. Thank you for answering my last question. If one's bedsheets are filthy with old zerah stains, and they are dry but they smell a little, would it be permitted to learn Torah silently, and/or daven in the presence of these sheets? If not, are there any lenient opinions who say it is permitted? Thanks a lot.
