Sounds like a band doesn't it?
XIPHOID PROCESS (Say it a couple times out loud. Fun huh?)
It's actually a pointy thing at the bottom of your sternum where the last ribs meet. While it is made of cartilage, the xiphoid process ossifies (becomes bony) in adults. When performing CPR, it is used to help locate proper hand placement for chest compressions. Care should be taken to avoid pressing on the xiphoid process itself during compressions as that can cause the pointy end to pierce the diaphragm. Which is super bad.
Oh wait, it is the name of a band.
