Tenacity is the true story of one man's courageous battle with
Parkinson's disease. At the height of his career as a successful cardiac
anesthesiologist, Jon is given a diagnosis that changes his perspective
and alters the course of his life. Rather than be overcome by fear, Jon
chooses to fight. His journey takes you from the wilds of the Arctic
tundra to the heights of the Rocky Mountains as he learns to seize
control of his life and his future.
from J. Annas Walker:
It takes a great
deal of gumption to stare a serious illness in the eye and not blink.
What I find compelling in Tenacity is how one man refuses to give up in
the face of adversity. He's forced into a version of retirement when his
health starts failing, but he doesn't just roll over and give into the
illness. He finds the strength to keep on going. He had to redefine his
life and what it meant to live fully, but he did so with great courage.
Tenacity isn't just one man's memoir. It's a study of the human
condition. I give Tenacity a full 5 stars
