People are jerks. Women in office buildings are worse. :P

I think that doing WW or any kind of weight loss program with that many people from work would be, quite possibly, the worst experience ever. You're bound to get at least one stupid asshole that's jealous because you're doing better than them.

Screw 'em - you're not doing it for them, for others...you're doing it for you. Kick ass, take names, and do what makes you happy. :)
