I'm alien. I entered this particular timestream in 1972 because,
   coming from that other dimension, it was the only way to enter.
   Through a womb, go through the annoying process of growing up,
   puberty and all that stuff.

   I'm approximately at the 1/2 way mark of my time here, perhaps a
   little more or less, but I'm getting closer to having a final
   report, which I hope to deliver sooner rather than later, as
   this species tends to degrade in its output capacities somewhat
   over time, even if their lateral thinking capacities increase
   over time.

   However, if it turns out the only way to deliver my report is by
   leaving this dimension... then I might stay the entire time.
