This woman is just absolutely remarkable. U.S. Rep. Gabrielle Giffords is defying all odds, and fighting for her life every second of every day. An update, published on December 16, explains what her weekly progress has been since getting shot in Tucson,  AZ, on January 8.

U.S. Rep. Gabrielle Giffords was upgraded from critical to serious condition Sunday after a procedure to remove her from a ventilator was successful.

Doctors have been positive, and at time almost giddy, in describing her progress since she was shot point blank in the head Jan. 8.

Giffords responded from the moment she arrived at the emergency room, at first just squeezing a doctor's hand. Then she raised two fingers. She opened her unbandaged eye shortly after President Barack Obama's bedside visit Wednesday. Then, more milestones -- which doctors said were all indicative of higher cognitive function -- were achieved, all with her husband, astronaut Mark Kelly, at her side.
