I'm 6' something and very thin, also I ride my bicycle like it's my job (i ride it a couple miles TO my job actually, every morning at 8:30) and drink at least 4 liters of water a day... So I suppose it does make sense, but it still weirds me out because I didn't expect this.

And Blindside that was the first thing I thought when she said it came back negative, which is why I seemed more astonished than delighted in my post.
