Similar to past tenses, tense backs are related to things that happened a while ago and are incomprehensible to most 5-year-olds. Brush up on the basics of back bliss with today's Groupon: for $35, you get a one-hour massage at A Kneaded Massage, on University Avenue (a $70 value).

At A Kneaded Massage, licensed massage therapist Patsy Ann Dugger eases the stresses and strains of weary muscles with her personalized care, expert execution, and hands. In the one-hour sinew-soothing session, Dugger exercises her specialty of alleviating headaches and lower-back pain, transforming taught, prickly puffer fish into sea-swimmers made of jelly. Clients may choose to manipulate muscles into good health with a pre-natal, therapeutic, relaxation, or stress-reduction massage, or choose to keep jealous skeletons from jumping ship with an orthopedic massage.
