With regards to sharpening skates, most of us conveniently forget how the narrow little bit of steel in the bottom of your skate, that's no more than 1/8" broad, may be the only point of contact among one's body and the surface from the ice. Because with this friction, the skate blade will miss its edge. It is essential to understand the relationship between the sharpness with the skate as well as the surface in the rink. If the skates haven't been correctly honed, even finest set of two skates are only of limited use and every one of your hockey skills can be of no use. Picture wanting to play hockey once you find it difficult standing up around the ice. However the humans living around the spaceship were different to the humans who are living on earth now. They were so fat that they are can not walk. they travelled around in motorised chairs having a computer screen and cup & straw attached, chatting on phones and if they happened to drop out they simply laid there until a robot emerged and picked them up. The adults were fat, your children were fat! They just laid around all day long meals doing no exercise what so ever and to quote the captain, "Computer, define dancing". The study of geology also encompasses Earth processes which can affect overall civilization. An earthquake can destroy a large number of lives in a few minutes. Also, tsunamis, floods, landslides, droughts, and volcanic activity may have an enormous influence on civilization. Geologists study those processes and can recommend action plans to minimize damage in the event that such events will occur. For example, by studying flood patterns of rivers, geologists can recommend areas to stop when building new cities,towns, and residential neighborhoods in order to prevent future damage. Earthquake science, although a very difficult division of study, might help minimize problems for life and civilization by estimating where earthquakes are likely to occur (referred to as fault lines) also to recommend the technology to use within the construction of buildings over these vulnerable areas.
