Edema is spelled edema in the States. The trouble with the 'experts' is many of them have consistently gotten this whole thing wrong. Go back and study the Chiang Mai 'experts' who propounded food poisoning, shellfish poisoning, seafood poisoning, and even said the 7 deaths in 4 different hotels around the same time-frame were 'coincidences'. Then you had the fatuous 'expert' governor of Chiang Mai saying he would eat a spoonful of chlorpyrifos (idiot would have died had he done that).
And then there is the so-called toxic waste expert, 'Dr' Ron McDowall, botching his investigation and coming to erroneous conclusions (see many posts above) saying it could have been chlorpyrifos by inhalation and making other ridiculous remarks (implying he's seen inhalation suicides with it when what he should have said is he's seen ingestion suicides).
And then of course there were/are the 'expert' Thai doctors saying it 'might' have been food poisoning, mushrooms, etc.
And lets not forget the 'experts' in the media swallowing whole all the bullshit spun by the Thais and sending this BS around the world: puffer fish, food poisoning, blahblahblah.
The world is run by 'experts' and look what a mess they've made of it. What we need are people who can think critically.
I don’t think you understand ethics very well.
