Astronomer, 72

I am a retired computer engieer who started education intending to do astrophysics. In retirement I am doing it, 5 years through a 7 year PhD program. I study, take walks, work on observatory data, and volunteer with a "Computers for Kids" organization. I live quietly with one cat. I'm looking for a quiet, educated, thoughtful woman, who will share her thoughts and consider mine respectfully. Intellegence, perspective, continual self education, and an unending need to learn are qualities I seek. Tolerance, mutual respect, patience, kindness, charity, and sense of humor are musts.
