Ben and Randy were in Central Park. Ben said, "I just bought a new bike. I'm going to ride around Manhattan this summer." Randy said, "I bought an 18-speed bike a year ago myself. I rode it almost every day last summer after work. You're going to enjoy riding around the city. It's fun and scenic." Ben said, "Well, why don't we ride together?" Randy said, "I'd love to, but I can't. My wife asked me to stop riding. She saw a biker injured near our apartment. It scared her. I don't have health insurance. If I get injured, she can't take time off from work to care for me at home. So, my bike is just collecting dust." Ben said, "Tell her you can't get any exercise without your bike." Randy said, "Oh, I still get exercise from my bike—every two months when I pump up the tires."
