yes, well, as you know, mh has said that the body seeks to get rid of ALL food,
it's all basically poison, so the grass is just like that, when the animals upchuck. But then again, he said you can live on it. And grow new teeth, etc. Fun story. Oh well, never mind. Think of it this way,
yes AND no.
on the other hand, maybe the nameless wheelchair guy just needed to do a lot of upchucking and expelling of 'putrid waste'. Think of it as a form of detox.
