My friend and I were just talking and she told me about this sub and what it's all about... And I never realized that the thing I've done as long as I can remember, throughout my days...

My dad has TMJ and, not knowing anything about it, I kind of just assumed my jaw was fucked up lol

As long as I can remember I've been able to rumble my ear in short but easily repeatable bursts.. I tried sustaining it for the first time today and held it for I think like 5 seconds. I'm blown away that this is a thing and that I've never known before lol
