For more than 20 years, I have warned clients about to file lawsuits and insurance claims to consider the appearance of their lifestyles and remarks made to others.

If your claims include physical limitations that leaves you nearly housebound, please think about the phone in your pocket or purse and the GPS in your vehicle.

Companies are reviewing policies regarding use of social media. The line between your private and professional life has never been fuzzier. Know your exposure.
