No ride today; weight issues

I'm self-employed and have ridden this economic roller-coaster the last few months (mostly heading straight down). Thankfully, some work has come in, but it's got me hopping to make deadlines, so I won't be able to get out for today's planned bike ride. Oh well. It looks pretty wet outside (finally) anyway.
Yesterday I checked my weight (which I do once a week) and was kind of surprised. I'm down to what I call my "race weight". I reached it a bit quicker than I expected to. Now I need to hold it there and not let it drop further. Here were the stats:
Wt: 149.8
Waist: 31.5"
Bodyfat%: 10.7
Resting HR: 45
I've now lost 14 lbs since January. I'm 5'11", so yes, I'm thin. In fact, my wife told me yesterday that I'm starting to get too skinny. We've been married 14 years, and she's been with me through a couple of these "running comebacks", in which I easily (sorry) drop weight. This is also the point where friends and family members start asking me in a serious & concerned fashion, "are you okay?" I'm built just like a pro marathoner (if only I could run like one!) In fact, when I ran track and xc in high school, I was 20 lbs lighter than this, and at the same height! I had no muscle (thankfully I do now). Some of my friends called me "Ethiopian Man", and not because of my Scandinavian complexion. Yes, it got to me, so right after I graduated, I tried to gain weight. I started lifting weights a few years later and have "bulked up" off an on (most recently in 2005), but that's really not who I am. Running is in my blood. If I have to be thin & look a bit gaunt, I'm sorry to those who are concerned. I feel healthier and more fit than I have in a long time. That being said, I'll be monitoring my weight pretty closely now that I've reached my goal. If that means I have to lift the ice cream embargo, so be it!
