Yeah, don't eat brains. I didn't find it rewarding, as I remember, and it's not worth the risk. On the other hand, there was at time when I couldn't resist pickled pig's feet. That time has passed. I won't eat a pig anymore... actually have tried not to eat any animal. But that is difficult to manage, for me, personally.
I always thought it was poverty that led to the consumption of feet, skin and brains, which I think don't have much nutritive value. Kidneys, hearts and livers, on the other hand are quite rich, aren't they?
Sicilians (my mother's heritage) are quite adept at using organ meat, so I grew up with this fare as part of my diet.
