Use your imagination. If your imagination machine isn't working, then your down and out for the count . My girlfriends grandfather is 77 years old and met a woman. Thinking in terms of age will make the path a dusty one.
Double check your wardrobe, you don't want to wear a jacket with elbow patches, or a baseball cap facing backwards. You probably knew that. Try libraries, coffee shops, outdoor seating restraunts or clubs (more free environment), cooking class, seminar on casual subjects; not grad school stuff. Or seek any place that has your interests so a woman there would expectedly have the same.
