I have some HP5+ that goes back to 2005. I've kept it in a cool dry place. Is it too old? Might it be slower or faster or what?

Four years is not very old. High speed film tends to become foggy faster than slow film but HP-5 should still be pretty much like new. I would use it normally but not for applications requiring pushing. A slight uniform fog has little or no effect other than to lower effective speed a little since it adds arithmetically to all densities. Other answer, you have to shoot some to find out if its still OK. A long time ago I bought a couple of bricks of Verichrome Pan. I kept them in the refrigerator but not the freezer. I used the last roll when it was ten years beyond the expiration date. It had become somewhat foggy but still made good printable negatives. A faster film would 
probably not have lasted that long.

Ahhhhh Verichrome - verily I miss thee (It's "Talk Like Shakespeare Day" here).
The subject line is really the premise of the old radio soap opera _The Romance of Helen Trent_, "The story that asks the question: can a woman find romance at 35 and... beyond?" 

    I am giving away MY age here...
