1-2'13 scientists found a dead body of a king in a parking lot in UK, and they were trying to discover any clues about his life.  they found a few roundworm eggs in his remains, since adult roundworm grow up to a bigger size than they found, while roundworm absorb nutrition from gut and produce 200,000 eggs per day, the scientist made a conclusion that the egg came from KING instead of soil contamination. when the eggs hatch, the king suffer pain. usuallly roundworm infect through beef /pork/fish which carry the paratise, but cooking prvents infection. the major way he get the roundworm is from water or raw food contaminated by faeces.
