I think that would make me lean towards logical subtype, and I think that could be a possibility. The physical description fits me better (see baby's thread), and it would make more sense of my introversion during childhood. However, the other factors don't really match so well; I may sometimes project an image of seriousness, but only to people who don't know me. Those in my "inner circle" see the goofy, bubbly, outgoing me to a much greater extent, but I think that's true of just about everyone. Is it possible that I'm the logical sub? Hmmm...
