Average time people keep their car?
The length of time varies with the make, model, and demographic, but typically 4 years.

I think it's due to a change in atmospheric pressure; if you go up or down the density of the air around varies. As you fall closer to the Earth's surface the density of the air increases (probably due to gravity). I think that the pressure of the air inside your ears should be equal to the pressure of the air surrounding you. Your ears should naturally adjust the pressure inside your head to account for any vertical movement, however too much vertical movement will be too much for your ears to change pressure levels without quickly evacuating air (which gives the popping sensation). You ears would most likely pop when you are in a helicopter or plane, also scuba divers employ measures to deliberately pop their ears as they descend (as water is a lot more pressured than air). You should notice that just before your ear pops, the quality of sound input will be poor, this is due to the bubble of air. Air can be evacuated through your nose. This can explain why you get ear aches when you have a cold. Ear popping can often relieve pain in your ear in such incidents. You can deliberately pop your ears by taking in a deep breath and closing your mouth, then pinch your nose with your finger and thumb and try to blow out all the air in your lungs through your nose (air shouldn't escape if you are holding your nose properly), the resulting density of air in your head will force your ear to pop. This is the trick divers use.

How do people control dog sleds?
Most sleds have a brake, and the dogs are trained to obey directional commands.
Some of the most common forms of these commands:
"Hike!" = move faster
"On by!" = continue in a straight line, ignore whatever you were looking at
"Gee!" = turn right
"Haw!" = turn left
"Easy!" = slow down
"Whoa!" = stop
"Let's go!" = start moving
Where does the Iditarode start?
The race has started in downtown Anchorage since 1983. The teams leave the start line at the corner of 4th and "D" at two minute intervals, starting at 10 a.m. It ends in Nome, Alaska. Every other year the trail is switched depending on if the year is even or odd, but it always starts and ends at the same spot!
NOTE: It's actually just a ceremonial start in Anchorage. The next day there is a restart on Willow Lake. That is when the real racing begins.
* Extra Note* I think that they should have the Iditarod on the Tv... but that's just me.

Snowmobiles replaced sled dogs as a form of transportation in remote northern areas.
