If you can, read Robert Caro's The Path To Power (Caro's The Power Broker has been a HN favorite ever since Aaron Swartz recommended it). It's the story of the first ~30 years of Lyndon B Johnson's life.

I forget which chapter it is, but Caro takes a detour where he describes the life of women during Johnson's childhood in the dirt-poor valley he was from: no electricity, no waterpower, everything in the house was done by women's hands, 24/7. There's a passage that stuck to me about how women in their 30s in that area looked like other area's women in their 70s, just a brutal life.
