Sticky Situation

I work in a building in Manhattan, and there always seems to be gum
stuck everywhere - people finish chewing their gum and they jam it
where ever they can find a crack. When I saw the movie "I Am Legend" I
thought it would be funny if the buildings all collapsed except for my
building because all the gum is holding it up.

Does gum decompose? Or is it like sap, where they find prehistoric
mosquitos frozen in chunks of it thousands of years later. If it is,
does that mean something like Jurassic Park can happen thousands of
years from now, where some race of creatures will clone me from dna
found in a wad of my spit in an old piece of gum?
