Watching Movies has positive or negetive effect?

Watching movies can effect your mind. It can be positive and negative. It can be positive if we watch movies for purpose of knowledge(e.g: if we want to be a comedian. We will watch comedy movies. They will also inspire us. They will also give us good key points on how we do it. It may also help in other ways)
Films also make us aware about different things. Like survival movies teaches us something about survival.

Films can also have negatives effects. First of all, sitting infront of T.V. or Computer for such a long time can effect our eyes. Secondly, today youngers are becoming very irresponsible. Sometimes they try to do things they see as they are immature. They dont understand that it fake. Sometimes they loose interest in studies, which can be very bad for their upcoming future. Watching horror movies or intense thriller or slasher or voilence and blood can be very bad for weak hearted people.

So we got some good news and some bad news ..

Why do we yawn?

Everybody yawns — from unborn babies to the oldest great-grandparent. Animals do it, too. But why, exactly, do people and animals yawn? No one knows for sure. But there are many theories (ideas) about why people yawn.

One is that when we are bored or tired, we just don’t breathe as deeply as we usually do. As this theory goes, our bodies take in less oxygen because our breathing has slowed. Therefore, yawning helps us bring more oxygeninto the blood and move more carbon dioxide out of the blood.

Yawning, then, would be an involuntary reflex (something we can’t really control) to help us control our oxygen and carbon dioxide levels. Sounds good, but other studies have shown that breathing more oxygen does not decrease yawning. Likewise, breathing more carbon dioxide does not increase yawning. Hmmm. Now what?

Another theory is that yawning stretches the lungs and lung tissue. Stretching and yawning may be a way to flex muscles and joints, increase heart rate, and feel more awake.

Other people believe that yawning is a protective reflex to redistribute the oil-like substance called surfactant (say: sur-FAK-tint) that helps keep lungs lubricated inside and keeps them from collapsing. So, if we didn’t yawn, according to this theory, taking a deep breath would become harder and harder — and that would not be good!

But there is one idea about yawning that everyone knows to be true. It seems contagious. If you yawn in class, you’ll probably notice a few other people will start yawning, too. Even thinking about yawning can get you yawning. How many times have you yawned while reading this article? We hope not many!

Whether you snort, cackle, chortle, or have a wild, weird little giggle, you have a “laugh print,” a personal signature that’s too, too you.

Laughter is so basic to humans, we barely notice it — unless it totally pleases or absolutely annoys us.

But laughter has power — the power to energize the hum-drum, add levity to the everyday blah-blah-blah. Laughter carries such a social connection that it’s a mating ritual, a way to bond. Studies suggest that laughter may boost our health.

Our all-too-human laughter sets us — and our close cousins, the primates — apart from all other species that roam our planet, says Robert R. Provine, PhD, a behavioral neurobiologist at the University of Maryland in Baltimore.

“Think about it the next time you walk through woods listening to the odd cries and calls of the creatures that live there: When you laugh, those creatures are hearing sounds that are just as odd and just as characteristic of our own species,” he writes in his book, Laughter: A Scientific Investigation.
