As far as how this stuff applies to objects with DFs, consider Smiley. He is just slime with a DF. My theory is that when Smiley ate the candy, it started a chemical reaction inside him that changed his body from slime to gas. Once the slime became gas, Smiley's body pretty much became too insubstantial to hold the DF powers. Especially after the gas began to spread and disperse. And when Smiley couldn't hold on to the DF powers, or the thing that gave him life, he "died".

But if that's true, other objects like Lasso and Funkfreed would be able to live forever. I don't think canons and swords die very easily. And they don't really age either.
