They are not always mutually exclusive, but if I had to choose between the two, I'd take the one which keeps your fingers attached when using power tools.
I recall reading the results of a study which claimed only 7% of the population is endowed with common sense.
I guess John Prine was right.
And you base your claim to having common sense on what? Your belief that anyone knows that a circuit with flashing LED's is a bomb? Like Regan said, the problem with liberals is that they know lots of things that just aren't so. Can you have common sense when you know something that just isn't so, like bombs might/must have flashing LED's.
Or is your view that common sense requires behaving in a manner that does not comport with common sense on the grounds that no one else has any common sense?
I have dealt with lots of things that have flashing LEDs, and I have dealt with lots of bombs, missiles, torpedoes and other explosive devices. So far the two piles separate cleanly into one or the other.
I have yet to experience a device with flashing leds that could or did blow up. I realize that Jack Bauer's experience is different. Maybe your claim to common sense rests on the fact that you watch a lot of TV.
