I always feel guilty for things I shouldn't, and not for things I should. One that falls into the former category is giving blood, which I haven't been able to do for 6 years now what with the perpetual parturition/lactational longevity. To assuage this misplaced guilt, I was poking around to find out about milk donation. I'm too much of a capitalist to donate my own personal self to this for-profit company, but I came across this in their FAQs and found it darn interesting:
Breast milk does have uses for adult diseases as well. People with cancer drink breast milk to calm their stomachs after chemotherapy, bolster their immune systems and help digest food. In some parts of the world, it is used for burn patients and organ transplant patients. If you are interested in donating your milk for these other uses, contact one of the 6 milk banks associated with the Human Milk Banking Association of North America (HMBANA).
