Rubenesque is the reality for women, not the exception

Thin was never the norm.

Indeed, starvation was never considered healthy, while overeating was considered showing respect for one's mother and the person who cooked the majority of meals in homes since prehistory.

Traditionally, men hunted and fished while women gathered roots, tended to both the garden and the hearth.

Hence, a healthy figure is the rubenesque one.

Today, it is known as BBW (http://en.wikipedia.org/wiki/BBW)
