You were voting before I was born?
My first election was in 1972, when I turned 21. The voting age had not yet dropped to 18 in 1970 (a vote which I witnessed sitting in the House gallery as a college freshman, and opposed at the time, and still tend to oppose actually, although I understand that all resistance is futile).
I believe my mother and dad started voting in the 1974 mid-terms and they both registered Republicans, which repulsed my grandmother, who was a Democrat at the time. That same grandmother switched parties in the late 1980s and is repulsed that her grandson (me) would be a registered Democrat.
