Question
Is Euthanasia allowed in the Torah? I'm learning about assisted suicide for class and was wondering how legal it was Halachically. The idea of ending suffering before natural death does not seem like a Jewish concept, but there are some opinions online that state otherwise. I'm just trying to understand if we are or aren't and what the reasons may be, (with sources.)

Question
I was able to hear an evening Megillah reading this year. But I missed the morning reading because I had to catch an early morning flight, which was unavoidable. I mentioned this to someone whom in turn told me that the mitzvah is to hear the reading twice, and if you listen to only one reading but not the other, you have not fulfilled any mitzvah at all. He said he learned that from his rabbi. Is that really true?

Question
Do dentures and braces have to be kosher according to Halacha? Is there something that has to be done before Pesach? What about meat or dairy?
