Brittle bones and fragile joints, exercise will save. Lose the use of what’s unused anxious doctors say, Tell us jog and walk and swim and dance a little, too. Now they’re saying life goes best if only we would screw. Thrust those hips, and arch that back. Feel those muscles strain. Keep on moving back and forth, ’till you feel that pain. Work up sweat and force that flush. Make your partner moan. It’s a sport you cannot play when you’re all alone. Seems they told me once or twice when my heart was young, Sex was something lovers did, sweet romantic fun. Now they tell me ’cause my bones have a mind to creak, Sex is something I must do, once or twice a week. Thrust those hips and arch that back, ’till we both are done. Keep on moving in and out — Oh, I’ve got to come. Work up sweat, and dream of love, of dancing in the sun. Would like to screw again? Loving you is fun.
