It can be partially lost, but I'm not sure if fully. I would imagine so though.
A ferret could possibly lose their sense of smell from an illness.
Smell
If you blow any smoke out of your nose it will damage it. You can and will lose your sense of smell and a lot of your sense of taste.
When you lose your sense of smell you begin to lose taste too. This happens because a large portion of your taste comes from smell.
The sense of smell is generally lost between ages 70-80. Also, it must be noted that it will be lost but not by some.
It depends on which part of the brain was injured - not all people lose their sense of smell. If the part of the brain that controls that sense is injured, then you will lose the ability because the brain cells are damaged and don't work to report smells like they used to.
Yes
nobody knows

Think about when you get a stuffy nose. When you lose your sense of smell it impairs your sense of taste.
If you lose your sense of smell your sense of taste generally goes with it, since the two senses are closely linked.
Yes there are people with no sense of smell, i think it can happen because of head/brain trauma
