You know what I really don't understand? My kidneys, and kidney function. I drink way too much my dew and stuff, but every year the numbers are perfect. So much, they even say they're amazed at my age how good the numbers are. I get occasional kidney stones, but I do drink a lot of "pop". Makes me feel bad because of Tiffany, I don't even like telling her they said everything was good, especially the kidneys.
