Why is your stomach making sounds?
Because I'm hungry.
The Answer:
Well, the answer is borborygmi. I know it's a crazy word, it kind of sounds like what happens when your stomach growls doesn't it? But, it's actually the name of the process where the walls of your intestines squeeze together to mix and digest food. Now, you will notice I said intestines and not stomach. That is because it really is not your stomach making those noises, it is further downstream after food passes out of your stomach. Sometimes you hear the growling when you're not hungry because your brain automatically turns the digestive system on and off several times a day. But digestion continues whether your stomach is full or empty. You just hear it more clearly and loudly when there is no food there to muffle the sounds.

Why do we celebrate Daddy's birthday?
Because Daddy was born on that day.
THE Answer:
Birthdays - and the annual observance of these times both as a society and for individuals - is the oldest of celebratory rites, and one that arose in every culture as soon as they had any sort of calendar.
The first real calendar has to do with the sun and the moon's position - the fundamental tools of astrologers today. The wise men (and women) noticed that when the sun hit the same spot in the heavens (against the zodiac backdrop) that it held on a person's birthday ... well, that day turned out to be extremely fortunate.
Maybe a woman found a husband, a shepherd saved his sheep, a merchant sold his goods or an illness vanished. Plus, people gave to the birthday person instinctively. So presents were bestowed - both from others and from the universe. The wise elders saw this phenomenon happening all the time. And just as most basic astrological information came about based on these days, the astrologer/priests saw that a "pattern" was occurring.
This lucky pattern brought joy, and thus the birthday person wanted to celebrate. His or her friends naturally gave to them (thus the idea of presents) and the birthday celebrant wanted to share his or her pleasure, so a big gathering was held.
That's the reason that we celebrate birthdays today - as a tradition that came about because of repeated observations of luck on this day.

Why is there Mother's Day?
Because moms are special and we like to give them this day as a "thank you".
THE Answer:
Mother's Day owes its origins to several long standing traditions in Europe and the UK where a specific Sunday was set aside to honor motherhood and mothers. Traditionally the day was marked by the giving of token gifts and the relinquishing of certain traditionally female tasks such as cooking and cleaning to other members of the family as a gesture of appreciation.
While the role of the woman has become less rigid in modern day society Mother's Day (or Mothering Sunday) as it has been called in the UK dating back to the sixteenth century, remains an important day for the honoring of the role that mother's play in the home and in society in general. There is a corresponding holiday for Fathers called, not surprisingly, Father's Day, but most sources site this as a more recent addition coming about in the late nineteenth and twentieth centuries.
While considered by many as a "Hallmark Holiday", ie. one with a purely commercial background, Mother's Day is actually a long standing tradition in the UK and several countries in Europe, and has cooresponding equivalents in many countries, including parts of India and many communities in Eastern Africa and the Far East.
Why is there wind?
To help us breathe better.
THE Answer:
Wind is caused by the uneven heating of the Earth by the Sun. Hot air rises (process of convection) and cooler air moves in to replace the displaced air. Wind is the horizontal component of convection which serves to redistribute the energy on Earth from regions of surplus energy (warmer air), to regions of deficit (cooler air). The vertical movement (up or down) of air causes different pressure gradients and air moves from regions of high pressure (cooler downward moving air) to regions of lower pressure (warmer upward moving air). The greater the rate of change (i.e. greater pressure gradient) of lines of air pressure between regions, the greater the movement of air and the faster the wind will blow. Direction of wind has to do with the pressure gradients and the Coriolis effect.

Why don't birds on wires get electrocuted?
God question.
THE Answer:
When the bird perches on a live wire, her body becomes charged--for the moment, it's at the same voltage as the wire. But no current flows into her body. A body is a poor conductor compared to copper wire, so there's no reason for electrons to take a detour through the bird. More importantly, electrons current flow from a region of high voltage to one of low voltage. The drifting current, in effect, ignores the bird.
But if a bird (or a power line worker) accidentally touches an electrical "ground" while in contact with the high-voltage wire, she completes an electrical circuit. A ground is a region of approximately zero voltage. The earth, and anything touching it that can conduct current, is the ground.
Like water flowing over a dam into a river, current surges through the bird (or person's) body on its way into the ground. Severe injury or death by electrocution is the result.
That's why a squirrel can run across an electrical line, but sadly die when its foot makes contact with the (grounded) transformer on the pole at wire's end.
It's also why drivers and passengers are warned to stay inside the car if it runs into a downed power line. Touching the ground with your foot would complete the circuit: Electrons would flow from the wire, into the car, and through you on their way into the earth. (Inside the car you are usually protected by the car's four rubber tires, which act as insulators between car and ground.)
