justification for macdonald's

The smile on the small little boy makes me realise that although macdonald's is unhealthy for the masses with its high amount of trans fat and what not, it still puts a smile on families as they munch happily on the fries or cakes. Life is simply too short to eat healthily and monotonously... After all, I think the joy of munching into that packet of fries offsets the knowledge of it staying in your stomach for days. But such is knowledge and exposure, for I still hesitate to purchase a mac meal no matter how happy it will possibly make me.
