Anxiety: We worry. A gallery of contributors count the ways. Recently, I found myself lying in bed, trying to sleep, a common occurrence. I had forgotten to call my mom back earlier, and I now pictured her standing in her kitchen. Then the next second she had aged 20 years in my mind, she needed help and I worried about where she and my dad would live, since my husband, kids and I are already packed in a 740-square-foot house. It’s common to worry more as you get older.
