why do we get static shocks?

Our Answer:
Because we have a lot of energy.


THE Answer:
Static electricity is generated whenever two materials are in contact with each other. All materials are made of electrical charges in the material atoms. In the universe there are equal amounts of negative electrical charge (electrons) and positive charge (protons). These generally try to stay in balance of equal amounts at every location.

However, when two materials are in contact, some of the charges redistribute by moving from one material to the other. This leaves an excess of positive charge on one material, and an equal negative charge on the other. When the materials move apart, each takes it's charge with it. One material becomes charged positively, and the other negatively.


why do we have lips?

Our Answer:
To give kisses.

THE Answer:
The lips are part of our sense organs. These as a whole detect our environment and allow us to alter our behaviour accordingly. An example would be my ears detecting a train coming and me getting off the track. Our lips contain many temperature sensors. If we consume food that is too hot, we may burn our tongue or mouth or throat, then those areas my swell up and prevent us breathing efficiently. Our lips prevent us from eating food that is potentially too hot.

why does it get dark sooner in nyc?

Our Answer:
Because we are up north.

THE Answer:
The earth it tilted 23.5 degrees in relation to the plane of the orbit around the sun. Because of that, we get seasons and right now, the sun is almost perpendicular over the Capricorn tropic, which is in the southern hemisphere.


Here, up north, the sun is much lower over the horizon and it gets up later and sets sooner. In the north of my country, Norway, the sun doesn't rise at all in December. It happens anywhere at the north of the polar circle.


why do we have hair in our armpits?

Our Answer:
I have no idea! All I know, is that it is very unfair for girls.

THE Answer:
While everything about our bodies appears to have some purpose, we haven't always discovered what the purpose might be. There are three things known about underarm hair:

1) It helps to keep the skin under your arms from rubbing against each other. Skin rubbing against skin can be irritating.
2) We have very productive sweat glands under our arms, but the location would normally trap the sweat against the skin. This would prevent the cooling effect that sweat is suppose to produce. The hairs keep a slight separation under the arms, allowing some air flow, but they also wick the moisture away from the skin to where air can carry the moisture away, instead of just running down your sides all the time.
3) Some theorize, and have some small evidence, that sweat glands under our arms and on our groins produce pheromones (scents that are sexually arousing). Like the second answer, the hairs make sure the scents are carried into the air. On the down side, bacteria love these moist areas, so if the underarms and groins are not kept clean, the smell of unwashed bodies overpowers the light scent of pheromones and causes the opposite reaction: "Ewh! You stink!"

why is Amaia eating from your boobie?

Our Answer:
Because babies eat from their mommies.

THE Answer:
Milk is produced in the milk-producing glands in the breasts, called alveoli. Milk collects in pockets, or lactiferous sinuses under the areola (the dark circle surrounding the nipple). Regular and effective breastfeeding or pumping stimulates the production of breastmilk by causing the release of hormones from the mother's pituitary gland. Prolactin and oxytocin are the hormones of breastfeeding.


why do we celebrate the new year?

Our Answer:
Because we have the chance to start fresh.


THE Answer:
Traditionally, the Roman calendar began the first day of March. However, it was in January (the eleventh month) when the consuls of ancient Rome assumed the government. Julius Caesar, in 47 BC, changed the system, creating the Julian calendar, with some modifications in the time of Marco Antonio consul in 44 BC, the emperor Augustus Caesar in 8 BC and finally by Pope Gregory XIII in 1582, is used today. This year begins on January 1. Subsequently, the Gregorian calendar had the habit and the celebration was marked with a religious significance during the Middle Ages and later centuries.

With the expansion of Western culture to the rest of the world during the twentieth century, the January 1 date became universal in nature, even in countries with their own New Year celebrations.
