Pointless non-thought
Totally random non-thought, "inspired" by mentioning in previous item that I'm getting enough protein from eggs and cheese.
The standard TEDX "evolution" line says that we descended from apes who mainly ate fruits and nuts and bugs, so we should be able to get along on fruits and nuts and bugs.
Why not eggs? When you're hanging in trees, bird nests are everywhere. Eggs are there for the taking just like apricots and acorns. Eggs are seasonal, but so are apricots.
