I was expecting such reply. In response I say this: have you guys used a sailboat? What do you do if you are in a sail boat and you want to sail upwind (against the direction of the wind)? Rookies would dispose the sails off and use the oars. Face the wind head on and fight against the nature. Tiring themselves. The more sensible ones, respect the might of the oncoming wind, and rather than fighting against it, use it for their own advantage by working their sails wisely. its called sailing close-hauled.
