Yeah, well part of this for me is dealing with a daughter who is prone to vasovagal syncope. Quite a scare for us the first time so we ended up getting a lesson on what it was from a pediatric neurologist. A lot less scary in subsequent episodes but it did get me thinking about the idea that so-called sleeper holds might be more subtle than we thought...
It's all good.
Well, except my daughter periodically passing out and smashing face first in to a wall or chair. That's not good.
