 If you have a frank deficiency of magnesium, that you can measure. But the subclinical deficiency affects so many different body parts, and it's very hard to measure. That's why I don't want to ignore this problem any longer. Very, very interesting. People are deficient. They have no idea. The good news is we're going to be able to fix it for people today. Now, Jan, you're very passionate about magnesium, and you are on something of a mission here, and you have been obsessed with this for the last few weeks, I have to say.
