I'll put those in quotes, because it's pictures of drops. And then the scale is eight people, eight people, let me write it this way, times eight people per drop. Eight people per drop. And so eight times eight, and actually even the drops, you can view them as canceling out if you view them as units, so drops, drops. Eight times eight is equal to 64 people. So they could have written literally the number 64 right over here. 64 people have type O positive blood.
