Where is me...
All gone for scalpels and stitches...

You can probably lose anything you don't absolutely need for important bodily functions such as circulation, breathing, digestion, waste elimination, and such Even some of the things you think you need are just niceties.

You wouldn't miss your spleen much, and you've got lots of superfluous intestines. Things NOT to lose include your brain, your heart, liver, at least one lung, and your sense of humor. (No, they can't take that away...)
