Bone Deep

I read in the newspaper this morning a report about the strength of prehistoric women's arms.  Although at first glance this falls into the "yeah, right, what else is new?" category, it was fascinating to view the list of chores that researchers think account for the difference:

Tilling the soil with digging sticks (the plow had yet to be invented)
Grinding the grain with stones
Milking goats or cows and processing the milk
Making pottery
Turning wool and skins into textiles

"We've largely been underestimating the scale of this work," said Alison McIntosh of Cambridge, an author of the report. All this physical activity produced bones that were larger and stronger — but also showed signs of strain. These long-ago women routinely did more than they should.

While the shin bones of modern female athletes compare to those of prehistoric women, the arm bones are another matter. The ancient women's bones appeared even stronger (and more strained) that those of current female crew team members.

I think of these prehistoric women digging and grinding, I think of my own puny arms, of my life of ease, sitting at a desk, typing words on a small keyboard.  It's good to be reminded of the difference.
