(See How Catalytic Converters Work for more details.). Controlling the engine is the most processor-intensive job on your car, and the engine control unit (ECU) is the most powerful computer on most cars.
â¢ Accidental poisoning is one of the leading causes of GI ulcer disease. This can be from plants (for example, toxic mushrooms, castor beans, or sago palm), pesticide or rodenticide toxicity, chemical poisoning (often with ethylene glycol or phenol), or heavy metal poisoning involving zinc, iron, or arsenic.
The symptoms can be made worse by your stomach acid. It is not entirely clear why ulcers start but stress and diet, especially a fatty diet, are big contributing factors. A higher intake of fat can greatly increase your chance of getting an ulcer in the first place and cause other gastrointestinal problems. High salt intake is also implicated.
