After learning about green burials and mushroom death suits, I’m wondering about halakhic implications of such burials. It seems to me that such methods for burial uphold the charge to go up to the dust even better than traditional burial where the body remains intact in a casket or even sometimes in a concrete box for a very long time. Should all Jews switch to a mushroom burial?

I was recently at a sporting event where the line to exit the bathroom took close to five minutes. How long following an action or event requiring a berakhah can you still make the berakhah? How does one behave while waiting for the opportunity if you are conscious of the fact that you need to make the berakhah but are temporarily unable and what ultimately severs the connection to the berakhah?

If I spend Passover with family members who don't kasher their kitchens for the holiday can I eat kosher for Passover food from their pots or dishes? Is there room for leniency because they're my family? 

What if my roommates want to use non-kosher for Passover dishes and products? How can we share the kitchen?

On a previous episode (Can You Make Seltzer on Shabbat? Responsa Radio #80), you mentioned that there is room to be lenient on the rules of food preparation when welcoming guests on Shabbat. Is that the really the case? If so, what are the limits?
