Science 15 : Watch out for the simple killers!

Hey, want to know some simple killers? Don't be surprised! Here's the lists and why :

1. Electronic games : Games(online or no internets) are just killing your eyes. These games stuff makes your eyes tired. Did you know... that most of the young patients has eyes problem? So then, try to less gaming on your electronic devices.
2. A very very cozy chair/bed : Really? well, that almost give me a loud laugh (LOL) right? Well, the effects of a very very cozy chair/bed is making you lazy to move and wants you to stays in your very very cozy chair/bed. The effects of laziness is less moving/activity(sports,etc.). And the long effects is diseases. You can have a risk having a heart attack, obesity, or diabetes. And when you get one of the disease, you are ready to go to the grave faster.
3. Sweets at night : Don't you dare to eat sweets before going to bed. "But I can brush my teeth later after eating one." Yeah, it's only you see it lightly. The problem is sweets containing sugar. Sugar is one of energy needed. But when it's not used, it'll be stocked to your blood. What the real problem is you could have a risk of diabetes. And more add plus you don't brush your teeth, I'll see you and laugh you 'cause your tooth are full of hole.
4. A Heavy Backpack : You could decreasing your height with this, just careful, don't too be short.

Okay, that's what I know. Just my advice : don't try this at anywhere, homes,hotels,or villa.

Science 14 : Opposite Directions

Do you know that every force (with directions) have an equal opposite directions? Well, it is already explained in Newton's 3rd law of motion. "Every directed force has an equal opposite directions". For some proof;

1. You stand on the ground on the earth.(Your force is directed to up, but gravity pulls you down)
2. You're holding a big stick about 2 meters high. But your friend kick at the bottom of the stick and the upper parts of the stick goes to your friend's head.(Yeah, this is what happening to me. I hold a stick, and 2 naughty students try to kick the bottom parts. One of them got his head knocked but I was blamed. I'm trying to explain it was the opposite force reactions. And he doesn't know, 'cause this happens when I was in grade 5. The name of the person is Andrean Salim. He makes Youtube videos too. And yeah, I don't know if now he knows about this... I don't like students at my elementary schools well. I explain them scientifically what's causing this, but they all blame me up. So that's why I decided to go to another school when I was in Middle School.)
3. And many else...

And this is the formula : F=m.a

Try to remember it....
