Hmm, seberapa akuratkah "best estimates" ini? Kok di situ tidak disebutkan dari mana asalnya? -- Ezda => S2D4 the World "Just marvel at man he sees by means of some gristle, and speaks by means of some flesh, and hears by means of a bone, and breathes by means of a perforation!" ~ Imam Ali (a) -- Berlombalah dalam karya, bersinergi, terapkan kaidah ilmu/teknologi serta kasih sayang dan manfaat untuk seisi alam, demi kebahagiaan dunia dan akhirat.
