      Cannabis is too easy to access (become more and more easy to access, as well).  People are under the influence that smoking cannabis is not bad for you, and that it is, in fact, better than smoking tobacco.  However, this is not the case, as researchers are starting to see that cannabis might actually be causing mental illnesses. 
  • most drug users take other drugs in addition to cannabis create methodological problems and explain the dearth of reliable evidence

      It is believed that cannabis triggers the onset or relapse of schizophrenia in predisposed people, however this cannot be certain, because many of the people being researched on have taken other drugs, which makes it hard to determine wether the triggers are from the cannabis or from any of the other drugs.

      During a test (that occurred over 15 years), it was discovered that by smoking marijuana during adolescence, you are increasing your risk of developing schizophrenia.  However, they are not certain that marijuana is the only cause: Other drugs might be a factor too, and a few other concepts. 
    • alicia waid

      In addition, research is showing that cannabis also has a relation with depression.  It was studied over a period of 15 years, and results show that by smoking cannabis, you are increasing your risk of developing a major depression.  It was also showed that the use of cannabis also increases the idea of suicide and inability to feel pleasure.

      alicia waid on 06 Apr 13
       
      Although only few studies were talked about in the National institution of Health, they are enough to prove that cannabis increases ones rist of developing schizophrenia AND depression.  The studies also provide very little support to prove that there is also a link between marijuana and mental health problems that are largely due to self medication (harder to prove).  These studies are not trying to say that if you smoke cannabis you will develop schizophrenia or depression, however it is saying that those who are more vulnerable will.  
    • alicia waid
      alicia waid on 06 Apr 13
       
      It is important to note that those who use cannabis must reduce their usage if they want their risk of developing schizophrenia or depression to decrease.  It was estimated that if you were to have reduced your exposure to cannabis, the incidence of psychosis would have reduced treatment by as much as 50% (Dutch study).

      In a Swedish study, it was proved that the use of cannabis increases your chances of developing schizophrenia by 30%.

      With further analysis, it has been discovered that cannabis is the drug associated with the possibility of developing schizophrenia (and not the impact of other drugs).

      During another experiment, it was found that 59 people with a basic diagnosis of a psychotic disorder show a strong association with the use of cannabis and psychosis.  It is evident that the longer you've been smoking the drug, the more your symtoms will worsen(there is a higher chance), just like with any other drug.

      In New Zealand, it was discovered that people who smoke marijuana are three times more likely to develop schizophrenia, by the age of 15 or 18.

      An Australian study was also made that shows the more you smoke cannabis, the higher your rates of anxiety or depression might be.  It was proven that this link is more prone to young women than young men, however this was not proved in any other study (except the australian one).  
    • alicia waid
      alicia waid on 06 Apr 13
       
      It was proven, however, that any young human being that has used cannabis three times or more by the age of 18 is more likely to have some sort of depressive disorder by the age of 26! (And unfortunately, this was proved even to those that stopped smoking cannabis and got themselves under control.  After the first 3 times, it was too late).

      These people who have family members affected by psychosis have approximately a 1 in 10 chance of developing the same condition themselves (even if they've never smoked pot).  However, if smoking marijuana, this doubles their risk (1 in 5 chance).

    *sticky note* exercise balances out the chemicals i our brain which helps our nerve cells. And if you don't know our whole body functions on nerve cells (like a messenger) so without exercise we can never really perform to the fullest.
  • Raghav Mohan on 06 Apr 13
     
    *sticky note* exercise also benefits us in many ways! for example: it avoids MAJOR stress from us. It also keeps us motivated and confident so that if ever a bad situation comes up, we would not go into a dull zone and become depressed.
  • Raghav Mohan on 06 Apr 13
     
    *sticky note* It's good to be happy when exercising. Exercise also helps our reparative cell (we begin to lose nerve tissue nearing our 30's). Exercise helps slow that process down by A LOT. Which helps us live on healthy lived. People you see in the newspaper or online that are 100 years old! They don't just magically get that old by just sitting on there couch eating junk. They EXERCISE everyday to stay fit.
  • Raghav Mohan on 06 Apr 13
     
    *sticky note* It helps generate new neurons which provides many benefits. Study shows that people who began exercising at there teen years and that are now 65-70 are much more active and healthy than any other 65-70 year olds.

    When someone experiences a stressful event, the amygdala, an area of the brain that contributes to emotional processing, sends a distress signal to the hypothalamus. This area of the brain functions like a command center, communicating with the rest of the body through the nervous system so that the person has the energy to fight or flee.

  • Both men and women rated symmetrical members of the opposite sex as more attractive and in better health than their less symmetrical counterparts. The differences can be just a few percent—perceivable though not necessarily noticeable.
  • "It makes sense to use symmetry variation in mate choice," said evolutionary biologist Randy Thornhill of the University of New Mexico. "If you choose a perfectly symmetrical partner and reproduce with them, your offspring will have a better chance of being symmetric and able to deal with perturbations."
  • Women with a WHR of 0.7—indicating a waist significantly narrower than the hips—are most desirable to men.
  • Psychologist Devendra Singh of the University of Texas studied people's waist-to-hip ratio (WHR).
  • 0.8 to 1.0 WHR in men is attractive to women, although having broad shoulders is more of a turn-on.
  • Where fat is deposited on the body is determined by sex hormones; testosterone in men and estrogen in women. If a woman produces the proper amount and mixture of estrogen, then her WHR will naturally fall into the desired range. The same goes for a male's testosterone.
  • "The idea is that beauty is conveying information about health and fertility, and we admire that,
  • Men's faces are shaped by testosterone, which helps develop a larger lower face and jaw and a prominent brow.
  • Research reported last month found women both smell and look more attractive to men at certain times of the month.

  • At the time of reward, nearly one-third of adolescent neurons became excited (shown in red) though the level of inhibition (in blue) changed marginally. Adult neurons registered much higher inhibitory activity and less excitation.

      This explains the science behind the difference in brain activity between adults and teens. The adult neurons reacted with less excitation and higher inhibitory. 
  • The extreme difference in brain activity provides a possible physiological explanation as to why teenagers are more prone than adults to rash behaviour, addiction, and mental diseases
  • "This could intensify the effect of reward on decision making and answer several questions regarding adolescent behaviour,
  • The type of erratic activity in the cortex that she and Sturman observed could aggravate these conditions at a time when the maturing brain is vulnerable.

    This article is interesting because it explains the science behind the difference in brain activity between adults and teens. It then gives a physiological explanation as to why teens are more prone then adults are to addiction, mental diseases, behavioural disorders and psychological illnesses. It speaks about different parts of the brain, relating them to their specific activities and then explains how this effects the teen negatively, while comparing everything with adults.

      This website is very interesting because it explains that their is an architectural difference in the brain of a psychopath compared to a healthy brain. The areas that are different are the amygdala, which is associated with emotions, fear and agression, and the oribitofrontal cortex (OFC), which is responsible for the decision making. There is white matter that connects the amygdala and the OFC, which is called uncinate fasciculus (UF). They found a significant reduction in the integrity of the small particles that compose the UF of psychopaths compared to control groups of people with the same age and IQ. The degree of abnormality was significantly related to the degree of psychopathy.

      Survival Stress is when your body reacts to danger by pumping adrenaline so you can fight off the dangerous moment. For example, if you were in a forest fire, your body would pump adrenaline so that you can run at intense speeds.
  • Internal Stress

      Internal Stress is when your body stresses about situation that you have no control over. This is a very dangerous kind of stress! Most mothers deal with this kind. For example, if their son or daughter were on a school trip and they were stressed about their safety and health but yet they can't do anything to help the situation.
  • Environmental Stress

      Environmental Stress is when your body reacts to the people around you, the noise or the amount of pressure you're under from either friends, work or family. For example, a student has a lot of work and their mom and dad have high expectations of their grades.

      Fatigue and Overwork stress is one of the hardest stresses to deal with. It happens when your body is over working and not knowing how to mange your time well. It's important that you take some time out of your day to relax. Often students and parents that have an intense job deal with this kind of stress.

      This answers the question to my TFAD project. 
  • Geniuses are those who "have the intelligence, enthusiasm, and endurance to acquire the needed expertise in a broadly valued domain of achievement" and who then make contributions to that field that are considered by peers to be both "original and highly exemplary."

      It's interesting to see that this question has been asked for a long time. If it were possible to produce a genius, would we eventually all live in a society filled with gifted individuals?

      There is a procedure to determine whether someone is a genius or not. 
  • the debate over what leads to genius has been dominated by a bitter, binary argument: is it nature or is it nurture — is genius genetically inherited, or are geniuses the products of stimulating and supportive homes?
