why dont you take a test. Live on your favourite mix of tubers for 6 months
and see how you go.

yes,  which proves my point about the premium of fat in the diet. they went
for other kangaroos, not tubers, and could leave the carcass *after* taking
the fat.   Perhaps it is too obvious to point out even for you that kidney

answer is nothing. So how did they survive and thrive without the blessed
grains and tubers?
