Why Keat Hwa 2 Boys Lost to Girls in Their Studies?
probably you will say they are lazy, stupid, wanna play with games with all sorts of reasonable answers.

BUT

After doing some research..
I found that the Boy's Toilet is doing the trick.
Do you all enter the boy's toilet before? If you have the chance to enter, for girls...I think you can stay in the toilet not more than 30 seconds.

The Situation of the Toilet:
1. Urine, some are on the floor of the toilet.
2. When urinate some do not flush the toilet and simply run away.
3. Some flush in the toilet is spoiled and you can imagine when they defecate the leave their feces there on the spot.
4. Other rare cases.

After tell you the situation of the toilet,
now I am going to tell you why Boys Lost to Girls in Their Studies is RELATED to the TOILET? (sure many people ask)

ok 1st Urine contain ammonia structure

.............O..............
.............||..............
H₂N-- C -- NH₂ (ammonia)

Most noticeably, the asphyxiating ammonia is produced by breakdown of urea. Urea is toxic and can be irritating to skin and eyes. High concentrations in the blood can cause damage to organs of the body. The Ammonium Ions fill in the air spaces of the toilet causing the toilet to have a pungent smell. So that's why you can stay in the toilet not more than 30 seconds. Besides that, Ammonium ions are toxic and can affect the nervous and respiratory system.

Moreover, when the 3rd case of the situation in the toilet happened, we boys will be in big trouble - 'the feces case'.

Feces is a by- product of everything you eat(simple saying). The main cause of the feces smells so 'great' is cause by hydrogen sulfide and bacterial action produce compounds such as indole, skatole , and thiolus (sulfur -containing compounds). The perceived bad odor of feces has been hypothesized to be a deterrent for humans, as consumption or touching it may result in sickness or infection.

Hydrogen sulfide is considered a broad-spectrum poison, meaning that it can poison several different systems in the body, although the nervous system is most affected. The toxicity of H₂S is comparable with that of hydrogen cyanide. It forms a complex bond with iron in the mitochondrial cytochrome enzyme thereby blocking oxygen from binding and stopping cellular respiration. Exposure to lower concentrations can result in eye irritation, a sore throat and cough, nausea, shortness of breath, and fluid in the lungs. Long-term, low-level exposure may result in fatigue, loss of appetite, headaches, irritability, poor memory, and dizziness.

Here is some fact:

• 0.0047 ppm is the recognition threshold, the concentration at which 50% of humans can detect the characteristic odor of hydrogen sulfide, normally described as resembling "a rotten egg".
• 10-20 ppm is the borderline concentration for eye irritation.
• 50-100 ppm leads to eye damage.
• At 150-250 ppm the olfactory nerve is paralyzed after a few inhalations, and the sense of smell disappears, often together with awareness of danger,
• 320-530 ppm leads to pulmonary edema with the possibility of death.
• 530-1000 ppm causes strong stimulation of the central nervous system and rapid breathing, leading to loss of breathing;
  • 800 ppm is the lethal concentration for 50% of humans for 5 minutes exposure.
• Concentrations over 1000 ppm cause immediate collapse with loss of breathing, even after inhalation of a single breath.

Problem: Why some boys sleep in the class?
Explanation: Because of inhalation of hydrogen sulfide causing them to fatigue and sleep.
Problem 2: Why mostly boys can't memorize facts well?
Explanation: Because inhalation of hydrogen sulfide causing them to have low memory.
(too much problems and explanation, the above is just an example)

Compare to girl's toilet their toilet i think do not have such trouble.
So Boys if you want to score well and be healthy don't go to the boy's toilet!!!
