Hi Sam, several sources write about Pasteur's last words on his deathbed which were quote:
"The pathogen is nothing; the terrain is everything." In the Truth About Cancer series this is discussed extensively. The second part of my sentence is a joke (edited accordingly). However, we can assume that Pasteur knew quite well what was going on.
In regards to your friend and the Healy: So good to hear that the device helped her as well. The more positive feedback we receive from genuine people, the better. Indeed, the device seems to provide a lot of help in the daily life however, the individual still needs to put in the work. Excellent news! I'm happy for her and thank you for sharing Sam! Appreciate it a lot.
