  • Fascinating topics & real science

    This is so necessary these days. I started following Eric Topol when Covid started and I am so glad I did. The information he freely shared with the public probably saved my life (I am still a novid here at the end of 2025) and today’s episode with Dr. Gunter couldn’t have come at a better time. I have been fighting for MHT for more than a year now & hot flashes are currently killing me. Now I can take some of this information in to my next appointment. Thank you both!!
