even if you'd know, be ready for a fight because by nature they try to survive, so it simply takes time to get rid of anything in your body, especially in the skin (I know this from my own experience)
do not forget that these microscopic bastards are very hard to remove, because they simply reproduce in very large quantities
I totally agree.
parasites are not in your body because you have done something bad and you must be punished. parasites are organisms and their goal is to survive and reproduce. Like all organisms on this planet.
What is unfair, is that a human female needs 9 months to make a baby. Many parasites make hundred of eggs and their growth is much quicker.
But the fight is not lost, because, as humans, we have a bigger brain which allow us to build more powerfull weapons of mass destruction (the war against parasites is a fair one, i think)
