Karen Hanrahan has been using the same McDonald's hamburger as a prop in her "Healthy Choices for Children" class since 1996 -- 12 years! -- and it's hardly aged a day in all that time. McDonald's should add "immortality" to its list of Unique Selling Propositions for its burgers (unless Karen has an ornate oil painting of the burger in her living room in which it slowly ages, grows mouldy, and decomposes).
1996 McDonalds Hamburger
The burger on the right, off the paper is a 2008 burger. I had to buy it to get the groovy paper and bag. The meat is a tad darker, the bun a little less golden but in 12 years it will look exactly like that too. Do you find this horrifying? McDonalds fills an empty space in your belly. It does nothing to nourish the cell, it is not a nutritious food. It is not a treat. I marvel at how McDonalds has infiltrated our entire world. A hamburger here tastes exactly the same in China or some around the world place.
