The antibiotic effect was originally discovered by French medical student Ernest Duchesne.
This is a big invention for medicine. It is probably the most important medical invention.
This medicine changed my life because if it didn't exist I could have died very easily. In this world it is very easy to get sick from infection, I can imagine this world if it didn't have cars, computers,an airon, electric stoves and calculators but I can't imagine this world without Penicillin, because I think this medicine is essential for in our lives.
BAD INVENTIONS.
War.
because I think that people invent the war only because they want have more power in the world and to give possessions of the earth and money, but this is very bad because allways innocent people die.
Sometimes I don't understand people. I don't know why the people invent the war or why the people try to kill other people, why?Sometimes I think, in this world there are only homosapiens and we are thise homosapiens, but when I see on T.V. a war, people fighting and people killing each other, I think maybe in this world there doesn't exist homosapiens.
