If you're looking to build up those arm muscles, you may want to try grinding grain (xay gạo) for hours a day.
Researchers have discovered the bones of women dating back 7,000 years (from the Neolithic Age — when farming first began) showed their arms were stronger than those of some of today's top female rowers (11 to 16 per cent stronger), and that they may be due to their highly agricultural lifestyle.
"They're farming without the plow or mechanized anything," Alison Macintosh, the Canadian lead researcher who is now with the University of Cambridge, told CBC News. "They have to till the soil by hand, with things like digging sticks and hoes. So that's a lot of manual work. And they also do all the planting and harvesting and the grinding of the grain to make flour.... That's a lot of manual labour."
