Question
I’m aware that most opinions are that swimming during the nine days is not allowed, unless it is for exercise and is not to cool off and is not enjoyable. Without making this a detailed discussion, I use swimming for exercise, which is important right now as I’m between multiple surgeries (trying to keep physically active and strong), but the truth is that I do enjoy swimming, and it IS something that cools me off, just by the fact that I live in an area with temps over 110 degrees. Am I permitted to swim 1) on Rosh Chodesh Av, and/or 2) during the nine days? Thank you.

Question
The Talmud Yerushalmi Yevamot 16:3 mentions an idea of using one’s facial features, such as their nose, to determine who they are. Are there any poskim who use this sugyah in the Gemara to pasken Halacha Lemaaseh that you can determine one’s status as Jewish or not based on their facial features/nose?

Question
If the first day of the 9 days is Rosh Chodesh, then why is that day observed as a day of mourning? On the contrast, if it is a day of mourning, then why is Hallel still recited?

Question
Dear Rabbi, Yesterday I was in the supermarket when a middle aged woman got angry at the customer service for a reason unknown to me. She then went on a profanity laced tirade in which she screamed at the employees. For most of the approximately 6 minutes this went on, I filmed the incident and showed the footage to my immediate family and a few friends. She then left quickly when she heard the police were on the way. As far as I know, her identity is unknown to the store and the police, and I surely have no idea who she is. The police just took a report, but because no money was stolen and no one was hurt, they don’t have any further plans to identify her. I have seen a lot of viral videos just like that on YouTube, taken by people who chose to film it just like I did. What I would like to know is if Jewish law permits publishing videos like this. I am concerned it could be Lashon Hara, or if any other laws prohibit posting this, since it is shameful to the woman who lost control.
