The four food groups are no longer beer, pizza, chips and cereal. You make thousands of dollars a year - and still can't afford that dream Porsche. You start eyeing the Light Beer Section appreciatively. Sleeping on the couch is a no-no. Naps are no longer available between noon and 6 p.m.
Sneakers are now 'weekend shoes'.
Pregnancy now brings thought of tax deductions instead of coronaries. The only drugs you take are Tums and Tylenol. The weak single you hit in the intramural softball game is now remembered as a Varsity dinger for the League Championship. You wear more ties in a week than you even owned while taking in college. You find yourself reminiscing fondly of 2-hour Calculus exams.
