Common Sense

Wouldn't the world be a much better place if people used common sense. Sometimes it just strikes me of how many people go about things as if they don't even think about what they are doing. In my Financial Services class, we talked about people getting loans for 500,000 when they may make a combined income of less than 100,000. As time goes on its like people don't even try to use common sense anymore which is sad because its probably the best kind of intelligence you could have.
