Do You Answer Calls From Unknown Numbers? [POLL]

Many people are complaining to the federal government about unwanted sales calls they are still receiving, despite having signed up for the national 'no-call' list that was put into effect about a decade ago.

Of course, it can be trying to deflect sales calls, or to interrupt something we are doing to answer a call that turns out to be a recording that tells me that I've won a great 'free contest' and all I have to do is pay them. Regardless, if I am free I often answer calls from unknown numbers. Do you?
