Murder case in the US. The ex-wife was identified by the serial numbers on her breast implants. Is everything numbered these days?

Pretty much, particularly medical stuff.

I would have thought any "spare parts" inserted into the human body will have serial numbers in case of problems. Then each individual part can be traced back to its manufacture.

Maybe that's the reason why cosmetic surgery is being encouraged. It's aplot to barcode us all.
