Yup, Bruce, Cindy Lou was/is quite a humanitarian. It doesn't erase the personality quirk that caused her to have an affair with a married man who was a noted philanderer but, hey, she was 25 at the time. More troubling is her addiction to painkillers 10 years later that caused her to engage in criminal behavior: stealing drugs from her own medical charity and forging prescriptions. I haven't found any info that says whether she still struggles with addiction problems or whether they're not an issue for her anymore.
