Question

Luciano Medrano, via Facebook asked:

I've read our bones inner tissue gets replaced by fat as we grow older, why does that happen?

Answer

We put this to Dr Ken Poole...

Ken -   Yes, it is true.  The fat cells are part of the same lineage as the bone cells.  So when we get older, we start making more fat cells and less bone forming cells, and that's an inevitable consequence within the bones.
