Yes. It is possible to seek a PhD at any point in one's life, although at some point you will shift over into the "unconventional student" category.

Some universities/faculty do tend to overlook unconventional students. However, if you keep publishing articles, learning new skills (and demonstrating them), and staying up to date on the research in your field (and demonstrating that you have), then you'll be in a good position to get accepted by the more open-minded universities whenever you decide to apply.
