Today I learned that I can tie my hair in a knot.

I also learned that mothers with type A or B blood do not develop IgG antibodies to fetal erythrocytes (they develop IgM antibodies) whereas mothers with type O blood will develop IgG antibodies which can cross the placenta and cause hemolytic disease of the newborn. And that's all separate from the Rh factor. I don't ever remember reading about that before but I thought it was pretty cool.

Three days until I take COMLEX. Nine days until I take USMLE. Head down. Power through.
