Tape worms LOVE to live in the brain where they are protected from the blood, it is only natural that their hormones and waste (poop) influences what we think and do.
To live to be 100 on drugs ONLY SHOWS that having less worms allows us to live much longer, because worms also can't live well on drugs.
To be wormfree and free of drugs and metals along with fruit diet a person probably have a very tuff time ever dieing, the human body is designed to NEVER DIE.
