-both  boys  in the  beginning  with  the  prescribed  poison doses  fell ill  but  slowly  and  steadily  their  immunity  got  used  to  it  and  normal  food   given  them  became  indigestible  , their  system  survived  and  thrived  on the  doses, insects  like  mosquitoes  , floes  and  others avoided them , if  there  was  a  bite  the  insect  lost  its  life,water  discharged  from their  waste was  absolutely  of  different  colour  from normal  ,they  even  took great  care  of  not  allowing  anyone  eat  out  of  their  plate because  it  got  contaminated the  moment  they  touched  it,
