“Every man has inside himself a parasitic being
who is acting not at all to his advantage.”

― WILLIAM S. BURROUGHS

If your pillow is more than 2 years old,
10% of its weight is mite faeces and dead mites.

Parasites can have their own parasites, and those parasites
can have parasites, too. Scientists call parasites of parasites
“hyperparasites”.

Humans are hosts to over 300 species of parasitic worms
and over 70 species of protozoa.

The mosquito is the deadliest creature on the planet.
Mosquitoes and the diseases they spread have killed
more people than all the wars in history combined.
