The health police

There's no denying it: exercise is good for you and a shot can help you dodge the flu; trans fats are bad for your heart and smoking hurts your lungs. We are treated to plenty of health information each day. But as anyone who has had a visit from the health police knows, hyper-healthy living isn't all fun and grains.

We're talking serious busybodies here. Whether you're charged by a friend, relative or total stranger, squad members are united in their mission to fix your health habits. It doesn't matter what you do--there they are, whistle in hand and ready to blow. Sure, they mean well, but armed with partial facts, the health police can be a real pain. So here we offer the straight goods on alleged health crimes--and a snappy comeback you can use when a health cop tries to clap the cuffs on you.
