Did you know that prolonged breath holding can be deadly? My topic for a health buzz is shallow water blackout. Shallow Water Blackout is a result of Hypoxia, or a lack of Oxygen to the brain. It is when your brain does not have enough oxygen, and has too much carbon dioxide, to tell the body to resurface. The first step to Shallow Water Blackout is hyperventilation, or rapid breathing. As you start to hold your breath, the O2 levels drop, and the CO2 levels rise. The next step is unconsciousness You black out. The last step, is drowning. There are a few ways to prevent Shallow Water Blackout. The first is to never swim alone. The next is to never hyperventilate. Another is to avoid playing breath holding games or exercises, and lastly, never resist the urge to breath.
A couple months ago, a high school student from ISB, a sister school, drowned. The cause was thought to be shallow water blackout. It was almost an hour before the school realized he was dead. This event can happen to anyone, even if you are fit and a regular swimmer. My connection to this topic is that I am a swimmer who spends a lot of time in the water. After researching, I found the preventions and causes of Shallow Water Blackout, and it is very important to know, because people are always trying to pass their limits.
I chose this picture because I thought that it was a cool slogan to show the results Shallow Water Blackout.
The images below discuss some perceptions boys and girls may have of the opposite gender. Have a chat with your partner about these perceptions and how they could lead to inaccurate generalizations of the opposite gender.
Check out the checklist below to see if you can tell which changes are just for boys, just for girls, and which changes boys and girls go through!
For those looking for definitions of certain terms, the vocabulary list below will help your understanding.

Paragraph 1 – What is your topic about
My topic is Autism. To put it simply, autism is the mental condition that is characterized by difficulty in communicating and forming relationships and using language. Autism is the lifelong developmental disorder, characterized by them, affects how we communicate with, and relate to others. It can be caused by genetic and cognitive problem of brain. The symptom of autism appears in infancy or childhood. It generally begins after the age of six month and continue through adulthood. Autism has many negative effects on the individual, family, and society. However, we looked into three ways to overcome this issue including education, medication, and alternative medicine.
Paragraph 2: What is your biggest learning from this?
My biggest learning from Autism is that there is no perfect cure of Autism so that Autism is a lifelong disorder. Also I learned that the discriminations are still existed and I think it should be disappeared by expanding education about disorders including Autism.
I chose this issue because i thought it was an interesting subject and that it could change the world. My dad’s company has a section that works on it, and he told me about it. I found it fascinating that genetic diseases (and other ones as well) could be treated by genes. Another thing that hooked me was that it can cure cancer which was previously extremely difficult to cure. This issue is relevant to me since we are teenagers right now, and by the time we grow into adults, this could be a vital part in our lives. Another way it could affect me (and other teenagers) is because other around us or us could need gene therapy.
While researching i learnt many things about gene therapy. One of things i learnt about it was what it does. Gene therapy either replaces a mutated gene (one that could cause diseases) with a healthy copy of the gene, “knocks out” (inactivates) a mutated gene (that again, isn’t working as it should be), or introduces a new gene to the body that helps fight the disease. Another thing i learnt is how its done. Usually, it’s done by using a harmless virus to carry genetic cargo into cells. There are two ways that gene therapy is performed; inside or outside the body. When it’s done inside the body, the doctors would inject the virus carrying the gene directly into the part of the body that has the mutated cells. When it’s done out of the body, blood or bone marrow is taken out of the patients’ body and immature (harmless) cells are separated out. Then, a gene is added into those cells and they are injected back into the patient. The last thing i learnt is that. The out of body method has been tested on children with immunodeficiancy (also known as SCID); a syndrome where patients are unable to fight infection, and often die in childhood. More than 30 patients with SCID have been treated using gene therapy, and more than 90% of them have been cured of this syndrome. A 90% success rate is extremely high. However, the 10% of children who were not cured instead developed cancer and died as they were unable to battle it. This is why it isn’t in use yet. My thinking has changed a lot over the course of this because before this i literally had no idea anything like this could ever exist. I believed that cancer was extremely hard to cure, and some genetic diseases were impossible to cure. Now i know that this is not the case, and instead it’s almost as if the genetic disorders are being stopped from their roots. However, we should be very sure that this is 100% successful before using it because it could make or break so someones life.
This relates to my topic because it shows a mutated gene being inactivated or knocked out OR a mutated gene being replaced by a healthy copy.
I chose to do my project on the affects of stress because when i made it my life was under a lot of stress due to friends and family. Stress is a hormone that is relist when the brain is under suppress. It was necessary for survival. It can keep people on your toes but if you have stress to often it can be bad. It can make you do rash desertions and give you and insecure felling.
I learned that it is important for you to have some stress but i learned that if you have a lot of stress you can not concentrate and you cant focus. It can make you thing some things are correct when you are not.
I chose cocaine because I had a friend in toronto who had a relative that had a cocaine addiction, this friend was very close to me. Cocaine ran his life and it was the only thing he thought or cared about. Cocaine had swallowed his life, and there was no way he could go back to his previous life. I learned that Cocaine also physically destroys the areas that you apply them to, like the nasal cavity if snorted.
I now think that cocaine is a highway to destroying your life because of the ways that it mentally addicts you to it, and the way that it causes you to rely on it in your lows and let it consume your physical and mental needs. Physically it causes the arteries to retract, this means that the cocaine travels through the lungs, into the blood stream and to the brain, the brain then associates the cocaine with a feel-good feeling and remembers it by that feeling and gots hooked, craving the drug.
Polio, or poliomyelitis, is a crippling and potentially deadly infectious disease. In areas with poor sanitation, the virus easily spreads through the fecal-oral route, via contaminated water or food. It is caused by the poliovirus. The virus spreads from person to person and can invade an infected person’s brain and spinal cord, causing paralysis (can’t move parts of the body). The reason I had chosen this topic is because I was curious about this topic.
