Date men from United States / Arizona / Nogales, 72 year old

Date a soulmate from Nogales, United States. Rather introverted.I am interested in science,math geography,history,animals and not interested in pseudo-sciences like psychology. I am retired on social security. Social work did not pay well. I am also interested in some technology. I built my own computed but I do not have a cell phone-They are too small.
