51. I've been a Star Trek fan since November 1975, when my grandfather wouldn't let me change the channel from that dumb-looking show with a pointy-eared guy to whatever cop show I really wanted to see. I was told to either sit down, shut up, and watch, or else go to my room.
So I sat down, shut up, and watched. Not too many days later, I started buying the Blish books, and thanks to Star Trek being shown 6 days a week on 3 different channels, I managed to catch most of them within a few months... except for the first half of "Conscience of the King." It took a couple of years for that.
By that time I was completely into science fiction on TV, science fiction movies, science fiction books, nonfiction science books, and my grandfather was becoming exasperated by my obsession with [strong Swedish accent]"dat damn silly Star Trek"[/strong Swedish accent]. I suppose the rapidly-increasing mountain of books in the house might have had something to do with that, although at that time he was reading my books faster than I was.
As for how I got to this forum... I don't honestly remember if it was because someone else recommended it, I saw a link, or just stumbled into it via Google. I probably have a post around here somewhere about it, from years back.
