@ Iaibear: I haven't yet. I'll place it on my 'to read' list, which is still rather long. It keeps growing.

Orienteerng sounds like fun, I haven't tried it yet. My sensei does so every now and then. (Hobby picked up doing service I guess; he wore green and maroon.)

I do plan on running races in the near future (5K ~ 15K). Need to get my speed up a bit, so does my VO2max.
