Too much information...L0L...
My brother has this deep fear that someone might get harvested just a tad early by a zealous meical worker.
Kind of like in the movie when Warren Beatty was removed (mistakenly) from his body by an angel too scared to watch the gore.
Call me fearful when it's not an emergency!
You might want to listen to your brother. No, it is not possible for someone to harvest too early...but sometimes it happens that patients are "labeled" as prospective donors and the talks with the family begins a bit prematurely...if you know what I mean.
