When I met Lenwa Joab in Enid, Oklahoma, last November, her health was already failing. She was 65, with a creased face and gray hair combed back with coconut oil. She sat silently in a wheelchair, watching her husband Ernest sweep a leaf blower across the yard of their brick rental home.
For several years, Lenwa had battled high blood pressure, diabetes, poor vision and, finally, a stroke. The effects were taking their toll. In a voice barely louder than a whisper, she said in her native language that she was tired — i mok — and needed to lie down.
