Nedarim 86: Who Owns a Wife's Body?

In memory and tribute of our teacher Rabbi Moshe Kahn z"l || More on the question of a vow about something that doesn't yet exist, in parallel to a field that is to be consecrated in the future, and why that parallel doesn't work... Until the Gemara figures out how it could work as a legitimate parallel. Also, what exactly does a husband own in the relationship, as tricky as that question may feel to us today? Does the wife have ownership over her body? The produce of her hands? Plus, a new mishnah: if a man mixes up who made the vow he's going to revoke, or he mixes up the nature of the vow, what exactly is his role here?
