Now their is no longer a standard of pollution is more of a standard of poisoning so that you make more money with Big Pharma. Sin that we don't know how many of them take the cancer. There are no statistics in this regard. With regard to the miles erased the industry has not done much to protect those who buy. There are systems to see how many miles it has done a car but I'm sure if you applied too much, the system is located. Just remove the cap of the engine oil already see the pieces of engine that if you measure with a micrometer, you know exactly how many miles has the vehicle. And then I think that we are cucuzze because they said "the head that does not speak is called cucuzza".
