Do you really want that fast food burger???

I heard from someone awhile ago that if I bought a burger and let it sit over a period of time that it would not rot. Hearing something like this, I had to test it for myself so I bought a burger from a famous fast food chain, I threw away the lettuce, onion and tomato leaving just the meat and the bun. I watched over a period of about a week and in the process, I expected it to rot and I was even concerned about it having a foul smell and my next concern was bugs. To my surprise, what happened was.......NOTHING!!!!!! So I put away, out of my site and actually forgot about it. Here it is now, 6 MONTHS LATER! It's still in tact, just hard as a rock. So it never broke down or disintegrated, is that something one should want to eat??? Can you imagine what happens when it's in your body? What an amazing and eye opening experiment!
