Reading. All the time. Pretty much anything I could pick up, I'd read. Encyclopaedias were heavy but I managed.
Watching classic Who and not being even remotely freaked out by the Daleks (the hiding-behind-the-couch thing made zero sense to me).
Almost every project I did in primary school was about space. Astronomy fascinated me from an early age.
Classic Who aside, if it was a TV SF series, I watched it. Even Lost in Space.
