text: You have stress incontinence--it happens when you laugh, sneeze or cough.  Especially  if you are female, have had a few kids, are over 50.  See a doctor--she/he can prescribe a medication (there are a few available).  Wear a thin pad & empty your bladder often.  Better yet, try kegel exercises--they are good for your bladder AND for your sex life! And don't stop laughing!
