It's not very clear what you like to tell us, dave:
- The more elements and groups, the higher the risk one glue layer could get foggy over the years? Yes. What's the news? ^_^
- The older (but also cheaper) the lens is, the more likely it can get foggy somewhere? Better foggy than fungus...
- "alive for the moment" - that's just what I can say about all my lenses - I also didn't manage to find a working crystal ball :lol:
