I am a 65 year old male living in the USA. I have been through 2 bouts of colon cancer, prostate cancer, esophageal cancer, lung cancer and skin cancer. I am currently cancer free as far as I know but I have experienced significant loss of lung function and am on 2L of oxyger 24/7. I am a big fan of red light therapy, grounding, living a circadian life, and managing my diseases and discomfort with devices that employ frequencies as a treatment modality. This includes the Spooky2 devices, and Qi Coils, MiraMate Majic Pro, and now the AHA Halo. My education background is a PH.D. in Biomedical health from the University of Maryland. In the 1970s and 1980s I was a practioner of Biofeedback training.
