By "old" I didn't mean actual biological age exactly. I guess the more appropriate word would be something more like "settled". As it stands, I have a mortgage and whatnot to take care of, it's not really realistic for me to quit my job and focus full-time on a PhD for the next 5-6 years.

That seems to be the consensus in the US for the most part. Ironically, it's actually easier for a working American to get a distance-learning PhD from a British university than it is to get a local PhD in person in the states.
Right now I'm in the process of trying to get into University of York's distance part-time PhD, while remaining in NY. It's a long shot but it's basically my only option.
