I'm a trekker: even though I was little, watched the first episode of TOS when it first aired (my dad is a big sci fi fan) and have watched all incarnations ever since.
I also watched the space program a lot. I was influenced by an episode of TOS where Uhura was under her console working on electronics. Hence, my dream was to work in the space program, on electronics. I was lucky enough to achieve this; I was a electrical systems technician at the Kennedy Space Center. I worked in the payload bay of the shuttle.
I just finished a degree in Biology and am about to embark on my second dream career, to teach biology in high school.
