When blood from a woman's menstrual cycle is recycled to it's purest form to be
employable for donation. This includes the

discharged from the vagina, that is not part of the usable blood.
Dave's girlfriend is on her period. She can help
save a lot of lives if she donates her blood by
hemovaginal desalination.
