Betcha didn’t know the world’s most famous naturalist actually knew a thing or two about solving pain... 

In fact, his philosophy behind pain-relief is much stronger (and more successful) than the laid-back physical therapy, revolving door of drugs, and questionable “quick fixes” most other medical professionals push. 

Darwin’s words, not mine: 

“It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.”
