What is In Common?

Last Question:

Why do you get Goose bumps? What purpose do they serve?

Answer:

Goose bumps are your body’s attempt to retain heat when you get cold. Small muscles raise the hair on your arms and legs in order to trap an insulating layer of warm air near your skin and prevent heat loss. Humans aren’t as hairy as in prior centuries. This biological response is probably not as effective as it was for our distant ancestors.

Last question:

What causes avalanches?

Answer:

An explosion or perhaps a gunshot can rigger an avalanche, but it is more likely the result of someone being in the wrong place at the wrong time. Stepping, skiing, or snowmobiling across a weak spot in the snow can cause a huge slab of snow to split off and tumble down the slope.

Last Question:

Will you will get sick if you go outside in the cold with wet hair.

Answer:

No, not necessarily.

You will feel very chilly, but you can’t catch a cold or flu just from going outdoors with wet hair. The common cold is caused by more than 100 kinds of viruses, not by feeling cold. Coming down with the sniffles was formerly thought to result from exposure to cold weather, a belief probably traceable to the fact that people tend to crowd together indoors when it’s chilly outside, causing a more efficient transmission of virus from person to person.
