Me and my brother started training in Tae Kwon Do in the '90s.
I started wondering what I was, in the '90s. And started reading 2 Encyclopedia sets, reading every National Geographic magazine I could get my hands on, and really finding out about the breadth and depth of my father's knowledge about History and people around the world (through all the questions I was asking him)... all to figure out the answer to the question of "what I was". This lead to or increased my passion for History, Anthropology, Archaeology, and Human Genetics. This also set me off on the process of reading all of those 2 encyclopedia sets, A-Z. (This was before most people had even heard of Internet or The Web.) And made me start to be appreciative of the knowledge I had access to from my father... from the all topics my father had educated himself on... and the very unique knowledge he gained by visiting every country in the world, except for two... and the knowledge he possed just by having been born in the 1920s.

My parents bought my brother his first car in the '90s (because he went to University). (It was a brand new black Chevrolet Cavalier.)
