Mako is another word for the spirits in the lifestream. It's the life of the planet, and the ShinRa decided to use it to create energy for everyday living. And, if you are infused it with, it pretty much gives your entire body a boost, but that's only a very small amount. The amount Cloud has in him. Mako poisoning is when the persons body cannot take the new cells, and the body rejects it. Shutting down the body. Severe mako poisoning, well, you're not moving, you're not talking, not eating, no memories, absolutely nothing. You're mind is dead, but the body and soul is still there. [Keep asking questions then! She feels smart when she talks this much!!]

[ooc: Yeah, it's really entertaining! ^-^ Or...I'm just a total dork...either way, it's sooooo much fun!! \o/]
