Well, I don't know what age most are but I have been having problems for atleast 10 years and it is worse now.I will be 55 this year. Have only had one child. Look out if I sneeze, I better find the bathroom before the next sneeze comes. My girlfriend makes fun of me and say I do the "John Wayne" walk when it hits me and I have to hurry to the bathroom. Have tried the exercise and several prescription meds. The last one I tried gave me dry mouth so bad. May have to look into some type of procedure.
