Who wants to be a volunteer?

Can you stand up and take out your phone?

Now imagine you are on a bus, with strangers surrounding
you, and you don’t want to talk to them. Then, you have your phone in your
hand, and start scrolling through social media. What would your posture be like
in this situation?

Can you maintain like this and put down your phone?

This angle might not seem as unnatural to our generation,
but it is actually equivalent to the angle of an 8 years old child sitting on
your neck.

You can go back to your seat now.

I have done extensive research that proves Canadians spend
around 5 hours on their phone per day on average, 7 days a week, 30 days a
month, for years now. And our body is gradually changing to adapt our habits
every day. When the spine is adapted to our unhealthy posture of sitting, it
becomes a spinal malfunction called kyphosis, which can only be fixed by
physical treatment, very painful indeed. Therefore, we should adjust our
posture of sitting and put the phone up to a higher elevation, so our spinal
angle can be fixed gradually.

Well, since the distance between our phone screen and our
eyes are getting closer and closer, our eyes are adapting to us looking at near
objects, and this is myopia. As we learned in science, the light rays only
focus on the retina when the object is placed close to your eye, and the image
would be blurry if placed far away because It would focus in front of the
retina. In fact, Dr. Mike, the lead investigator and clinical scientist of the
Waterloo university says that: “Historically, myopia started at age 12 or 13,
but now it is showing up more often in kids of six or seven years old.” In the
1970s, only a quarter of North American population suffered nearsightedness,
and now the number has doubled. It’s even affecting nearly 80 to 90% of some
Asian country population.

But what makes it so hard to put down?

Take for example a racing game. when you break the old
record, and you are achieving goals and your brain releases a portion of
dopamine. Since you broke your record, the game would reword you with faster
and better cars, which cause your brain to release more dopamine. And this
eventually becomes the compulsion loop. And it is also the exact same loop that
is causing the addition from serious drugs. We are never truly alone on the
internet, social media, we never have the be bored under these constant feeds
of information. Therefore, Compulsion loops can also be found in apps on our
phone. They are designed to constantly provide new content, and making them
especially hard to put down.

The phone is changing your brain too.

There are two types of brain patterns: Alpha waves and gamma

Alpha waves often connect to relaxation and associated with
focusing ability.

Gamma wave often connects to conscious attentiveness, like
doing math or physics.

In fact, experiments have shown that when a cell phone is
transmitting, like during a phone call, the power of alpha waves is
significantly boosted, means that phone transmission can literally change your

Since we use our phone so much, what does learning matter if
all of the information in the world is just a Google search away? if that’s the
way you are using your mind, just searching on the internet, finding
information, and forgetting them very quickly, you are not building knowledge.
You are simply thinking like a computer. Which means that the humanity is at
stake, and it would be a shame if everyone is assimilated. If you look at the
great monuments of culture, they come from people who are able to pay
attention, who control their mind. And that’s what makes our mind to think more
critically, and in a creative way. 

So, overall. Phones are great in many way, and extremely
useful when you need to check something online. But, many successful
businessmen would take a smart phone vacation in order to increase
productivity. So guys, try to take one day off from your phone and you will see
the differences. Thanks for listening.
