Submitted by Yuki Seno on Sun, 03/05/2006 - 15:23.The positive and negative inventions
I think that the positive invenions in our world are electric appliances, security alarms, medical treatment devices.
but I think medical treatment devices are the most important. because people sometimes
become sick and have a sudden accidents. From light accidents to heavy accidents. Those people can be helped just because There are medical treatment devices.
For example, having a headache, suffering from a convulsions of the body, feeling nauseated,eyesight obstacle have symptoms. When it is investigated by MRI (Magnetic Resonance Imaging) the method of brain tumor was discovered. It allowed for early detection of cancer by using PET (Positron Emission Tomography) recentry.
I think that the negative inventions in our world are wire tap, gun, virtual reality games.
but I think VRgames are the worst inventions. because the game popularly has both children and adults. Recently, the game which carries out homicide and fighting is put on the market. It has had the worst influence on children by the game. Recently, the crime by the boy is increasing in Japan.
The child who committed the crime has said in this way.
"I thought that it revived even if killed."
I hope that an excessive game does not promote more crime.
