I think that fast food is like slow death because there side effcts or lets Say her serious and dangerous affect appears by the time .beside  fastfood are like smoking {we know all that it kills but people keep smoking} Same as fast foods because we all know that is dangerous but our style of life ,the speed and the system of our world make us like machins .we chase time and fast food is one those solutions but we  dont have choice .I think that  the solution is between the hands of big companies like{ macdonald and pizzahot and kintaki} all those could make a big change  and maybe solve the problem  by improving the quality of  food and go more To the natural and healthy food.
