I've always wondered what would happen if I left items for a long period of time- how long does it take to make things spoil, go bad, rot, fall apart, or disinegrate. 

This blog talks about the effects that time, humidity, and temperature had on a storage unit that was left alone for 11 years.  When they came back to the unit they were able to see the condition of their belongings.  Read the blog to find out more about it.  Very interesting and good to know what will last and what won't last.
