Discussion Question 4/13

If someone discovers a cure for the common cold, I believe that they should keep it a secret, because the common cold is not neccessarily life-threatening. In fact, everybody gets it- it is a regular thing. If it was a cure for Cancer, then definetly yes, they should tell everyone about it. But, with the cold, it is just something that comes and goes, it is not that big of a deal. And, workers will benefit more than people who get the cold. Because, common cold is temporary, jobs are not supposed to be. That's why people usually react negatively to advances in technology, and because their not always sure whether or not the technology will work and how it will it will effect people.
