Por que Harv estava doente na Idade dos Diamantes?

A doença vem de toda a nano tecnologia no ar.

Part the First, Nell sees some­thing pe­cu­liar; Harv ex­plains all:

"See, there's mites around, all the time...They're in the air, in food and water, every­where. And there's rules that these mites are sup­posed to fol­low, and those rules are called pro­to­cols. And there's a pro­to­col from way back that says they're sup­posed to be good for your lungs. They're sup­posed to break down into safe pieces if you breathe one in­side of you." Harv paused at this point, the­atri­cally, to sum­mon forth one more ebon loo­gie, which Nell guessed must be swim­ming with safe mite bits. "But there are peo­ple who break those rules some­times. Who don't fol­low the pro­to­cols. And I guess if there's too many mites in the air all break­ing down in­side your lungs, mil­lions– well maybe those safe pieces aren't so safe if there's mil­lions."
