they can get old, they can get dry rot, they can mold...you just do the tug test..if it seems to break easily then spritz with water and place in a ziploc or covered plastic dish in the fridge for a few days to rehydrate the thread. Of course this only works on 100% or silk..not on blends..if a blend breaks easily toss it out or keep it for sewing on buttons!
