What is the punchline? What factors explain absence of pancreatic cancer? I could not read the last part.
The punchline essentially is 1) make sure your drinking water is clean; 2) control your weight (avoid over-eating, try intermittent fasting); 3) make sure you avoid stress. Exercise isn’t as good as simply constructive movement, like gardening. Do things that make your body move, but don’t create more stress.
The avoidance of bad drinking water seems to be extremely important. Check where your water is coming from.
