那為什麼高山滑雪賽沒有人在衝個終點時身體是站高來衝，

那如果兩人都不帶雪杖，站高跟蹲下，那個風阻小，直衝下山，那個比較快

The one with the lesser frontal area and lesser movements will have lesser wind resistance, so when all else are equal (which is really not so realistic), the one with the lesser frontal area goes faster, presumably, but for “skiing”itself, the “skills” are not so straight forward.

Speed and the maneuverability don’t complement to each other, which means if you go straight fast, you cannot turn as faster as the slower speed can, so you lose your maneuverability.

There are two races here: a downhill racer skis in his or her “private” line without the fear of hitting or been hit by anyone, which is like a race car driver drives on a race course, so he or she can go as faster as they could, of course they are faster; another one is a recreational skier skiing in a crowded ski resort, dodging in and out the traffic among all those “flatlanders” and “weekend warriors,” which is like driving through a metropolitan freeway traffic. While they both get down the hill “equally,” which one do you think is more “skillful”?

Of course the racer is more skillful, that's a stupid question.

We are talking about wind resisitant, not skill.

Not sure if the question is stupid, or the answer is stupid. All these old gazers maybe were “ex” something, but now no longer holding any titles; by my observation, they can out skiing at least 90% of the skiers on the hills, on and off the piste. So, if you are not the top 10% racers, they'll definitely make you work for your titles.

“Skill” IS about how to handle the technical issues such as “wind resistance” to minimize its negative effects.
