Wow, this is amazing. I remember some time back reading about fetal cells remaining in the mother’s body, but this report also says that those cells are active and can affect the mother’s health.
While the cells can have a detrimental affect (I’ve bookmarked a couple of the links to read later), it seems that in a lot of ways, the cells improve the mother’s health. I wonder if this is possibly a contributor to women living longer than men?
