I've no idea what your glue may be, but if/when you find out, I think I'd like to have some of it (LOL).
All glues 'dry out' or get brittle over time. Epoxy glues tend to 'turn loose' when heat is applied (pray the melting temperature of the two things it sticks together is higher than the epoxy's melting point!). The 'mek' type glues don't 'dry out' since they actually 'melt' the two surfaces together (plastic), but it's problem is that the joint tends to shrink over time, causing a weak spot. That time period isn't a problem in most cases, but it does happen.

(This is strictly a personal observation so take it for what it's worth.) My models have a limited life span. Either because I do something 'dumb' and break them, or because I loose interest in them. So, almost any glue will last as long as the model does. You have a choice when selecting a glue, ease of use or longevity (among other considerations). I look for a reasonable 'life span' from glue, and since I'm lazy I want an 'easy/fast' glue to use. The two are not always compatible. So for me, the definition of 'reasonable' is variable. You 'pays your money and takes your choice'...
