Four or five years ago, my local hardware had bottles of Tite Bond LHG clearanced out for $0.79 a bottle. They were, of course, past the date on the bottle but, nevertheless, I bought all they had on the hope that they would still be good. It was cheap enough to risk it. I didn't notice any problem with the glue at all until about 2 years ago, when I had face glued two pieces of cherry together and the glue failed horribly and actually molded on the work piece. So, the glue would have been at least three years past expiration at that point. I did keep the glue in my basement which is pretty much 55 degrees year round so I'm sure that helped.
Your endgrain is like your bellybutton. Yes, I know you have it. No, I don't want to see it.
