Braining has been around for a long time but I've never talked with someone who's done it. I've got a strong stomach and that's pretty disgusting. I'd rather cough up the extra 4$ for a gerbil than go opening up skulls. Balls go absolutely insane for gerbils. Ever since I learned about prions I can't say I'd be excited about playing around with brain matter.
It's really not a big deal guys, you don't see brain bits, or smell brain, or touch them, or anything. Just.... poke the head? Honestly.
