I've been thinking for a long time about what happen to these children. I haven't been convinced of adrenochrome yet. If it's not adrenochrome, what could the elites be using childrens' bodies for?

My best guess so far is bone marrow. We have seen the rise of of using young blood to help older bodies repair themselves. The life of the blood cells is measured in days. What if you could have bone marrow from the young transplanted in your body and have it continually produce the better blood? Would it give you better health? Better energy? Better looks?

I do not know how much bone marrow is transplanted in the usual surgery but I'd imagine to get a sufficient amount for a full grown person, a child size body would have to be drained past the point of survival.

Am I over thinking this or am I going down the right path?
