Old enough to know better... but I just, kinda, never got the message.   Call it what you will... following a different path, late-starter,  whatever... I have just always felt slightly out of phase with most of the world around me.
I've always been an avid reader, though, of several genres including thriller, science fiction, mystery, horror, fantasy, and more.   This, I think, kept me sane... I think. (oops, already said that).
A few years ago, I had an idea for a plot and sat down in front of my PC and started writing.   I haven't stopped since then.    I found one story led to another, and another, and... you get the idea.    I am addicted.    I cannot stop.    If reading keeps me sane, writing adds to my sanity.  (is that possible?)
