I remember reading once that it is still not understood how the giraffe manages to pump an adequate blood supply all the way up to its head; but it is hard to imagine that anyone would therefore conclude that giraffes do not have long necks - Robert Solow

Quoted in Mankiw, G. (2006) “The Macroeconomist as Scientist and Engineer”. Available at: So, everything is possible. there remains an imperative to dream like a giraffe. i wonder how big a giraffe’s heart is? hmm, that would be definitely procrastinating. oh, they are beautiful and noble animals, with their piny blue drool swaying in the breeze.
