Ever since I moved into my Colonial-style home (built in 1941), the ceramic tile floors in my kitchen and bathrooms have been a constant source of frustration for me. No matter how vigorously I mopped ...

Recently, a man visiting his parents’ newly renovated home recognized an eerily familiar white curve in their tile floor. To the man, a dentist, it looked just like a jawbone.
