> i'm surprised they made is this long without some sort of organ issue yet their 4 (more like 3) tiny lungs, 2 tiny hearts, 2 tiny stomaches, and 3 kidneys all provide ample support when functioning together. their shared liver and pancreas are larger than average to accommodate both of them. they would only have issues if one sides stopped working. you'd also have issues if half of your organs failed, but your brain controls all of them.  one thing i also remember for their tlc show was that one feels the other's stomach. so, if one died, she'd no longer have her sister to be able to tell her how her stomach felt. that could lead to issues in itself when ill, eating a lot, or trying diagnosis an issue.
