For Dori; About eating grass:
I understand it is the cellulose that is indigestible.
Cows eat grass- they have four stomachs and they chew it
twice.
Dogs eat grass probably as a catalyst or laxative.
Black Bears eat grass in the spring when they first come out
of hibernation; probably it has a special effect.
Some people eat wheatgrass- whatever that is.
Back to the cellulose- Termites eat wood- they cannot
digest the cellulose but they have bacteria in their gut
that digests it.
SO maybe if you eat some wood termites first; then you can
eat grass!
Good Luck, Lorenzo
