@tilscience: Science just proved that the phrase “I feel it in my bones” is a real thing. Apparently, your skeleton is involved in your fight-or-flight response.

The strangest part is that osteocalcin comes entirely from bone cells but has almost no effect on bone density itself. Read more: Moser SC, van der Eerden BCJ.
