Is stretching before working out important?

Yes, you can twist or break parts of your body if you do not stretch before working out. It is always important to stretch even if you are doing activities such as gymnastics and karate.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
