On a weird note... I don't understand why everyone uses this saying? Bones aren't dry -- they're spongey on the inside with marrow where your (red) blood cells are produced. If your bone is dry, it's probably because you have osteroperosis... or are dead. ^^;; In which case it would just be easier to say my product is dead lol.
Lol - same sayings are just fun I suppose. I could go into empty marrow supplies...but that would be too much (yay for experiences in Oncology nursing)
