I got 12%!!!
I went to collect Finn from a friend's house recently, and while I was chatting to the mother of his friend, she filled a glass with water and had a few sips. We kept chatting and she suddenly tipped the water out and filled the glass again from the tap. She took a couple of sips and while we still talked, she did that again. By the time I left, she had refilled her glass five times, and sipped each one only once or twice. She seemed completely unaware of her actions. It was most disconcerting.
Not to mention a terrible waste of water!
I got 46% must be a good day, thought it would be higher. You know when you pour the water in to a glass from the tap so fast that bubbles appear? Well, when I was younger I had major heart problems, and I used to believe that if I drank the bubbles from the top of the glass, that I would have more energy! I must have wasted so much water as I stood at the sink continually refilling the glass just to get the top inch of water/bubbles. I guess all it was doing was giving me a supply of cold tap water to cool me down.
