Office Genetics So, in my office we have a sales team and an operations team.  The sales team is primarily young (20's) types and thin. I run into many of them at the gym.  The ops team is primarily older (40's, 50's) and ALL obese. One has had both hips replaced and another is constantly ill. Anyway, today the sales team brought in a huge vegetable tray with hummus. The ops team brought in multiple boxes of donuts and kolaches (sausage and cheese wrapped in a donut). But, the people on the ops team just can't seem to lose the weight. Must be youth and genetics.
