I use Titebond of various types all the time, you will have no issue with it provided it is kept at a fairly consistent temprature. I could be wrong, but I don't believe Titebond original is a PVA glue?
Bear in mind it is a water based product so dramatic changes in temp will affect it over a period of time. However, if your workshop is uninsulated keep it in a cabinet. That way it will literally last for years.
If the glue develops small pin head lumps it has been affected by adverse temprature conditions and should not be used. This happened to me once with a bottle left in a shed, lesson learned.
The other thing to be careful of is, if you are working on large projects with multiple joints then this glue is not for you as the open time of the glue is very short, just a few minutes. In this instance use PVA as it has a longer open time.
Good luck
