It's the "humorous" side of owning older lenses JoJu! 
In the event of lenses having individual elements (no couplets) your only risk is fungus, which for the most part is easily cleanable (at the "possible" loss of a tiny amount of coating).
With fogging your lens is dead!
It's a bit like owning a car with no electronics around the engine, at worst you have only to change the points or the coil!
