expired but OK!

Hi, some weeks ago in my garage I found two Provia 400 Fujifilm cartridges which had expired in the year 2000, they were kept sometimes in summer under temperatures of more then 35 degrees C. during more then 9 years. I asked the forum if they thought it was worth while to try to shoot them and they encouraged me to try. I did and I was surprised the dias didn´t show any detectable defect as far as I am able to see.
greetings to everybody
