19? 19???!!!!
Man, when I was 19, the VietNam war was still raging, Nixon had just been elected a year prior, I had a dial telephone, 45 rpm singles were still being sold, the 8-track tape player had just come out, and there were--gasp--no personal computers. Just big mainframes with a whopping 64K of RAM.
As for shaving, when I was 19 or so, my brother, who was a plastics engineer, had an idea for a plastic, disposable razor. Nothing like it on the market at that time.
