All fish have parasites & pathogens.
A successful parasite does not kill the host.
The Japanese people have a high rate of parasite infection caused by eating raw fish.
Some parasites go unnoticed, others cause gastrointestinal distress. Some parasites need to be surgically removed, like the one guy in Japan with the worm in his brain.
>> The Japanese people have a high rate of parasite infection <<
Well, that fact (factoid?) must explain why they have the world’s highest rate of life expectancy!
In other words, gimme some parasites!
