I like to guide your attention to the work of Denis Sciama who in his article "On the origin of inertia" (see reference below) has put a very interesting view not only on the origin of inertia, but also on the origin of gravity. His approach is only very very indirectly related with entropy. However, his approach includes the influence of the whole of the universe.
A 19th century nursery rhyme called "What Are Little Boys Made Of?" and generally attributed to Robert Southey goes

"What are little boys made of?  What are little boys made of? Snips and snails and puppy-dogs' tails, that's what little boys are made of.
What are little girls made of? What are little girls made of? Sugar and spice and everything nice,
that's what little girls are made of."

But these days in Australia both genders, even only four weeks old, are made of sugar.  And salt and high-fat foods, despite health authorities recommending exclusive breastfeeding to six months of age.
