 And a lot of them did volunteer. Thousands of children. About 5,000 or so children. Well, I think it's wonderful that they have this, and I'm glad that I'm participating. I actually found this old documentary from when these tests were being done, and it's just a room full of these kids getting a vaccine shot, crying, and then these mothers. I'm here because I feel that if this will help children, this will be a wonderful thing.
