I was thinking about how if you try to hold your breath your body will cause you to involuntarily breathe and I was wondering if this would apply to Feruchemy. Would you be able to store so much health in a goldmine at once that you are in such a horrible state you just die, or maybe store so much heat in a brassmind your body freezes? [After looking on the Coppermind it said they would pass out, but maybe someone taking drugs could bypass this?] Would this also work when tapping a brassmind, could you tap all your stored heat in such a short span of time your body just burns up? With the potential for Mistborn to take a darker turn as the eras progress I thought it could interesting to consider. My real question is really would your body stop you from storing or tapping some amount that would be lethal?
