I have a different kind of health problem that gets in the way of my exercise routine. Maybe TMI? I have a prolapse (thanks to 2 babies) that makes me have to use the bathroom AT LEAST once an hour. Which makes my walk/jog route almost always the same. I go around the park because it has bathrooms. When winter comes and they lock up the bathrooms, I move to the indoor walking track - so I can have a bathroom nearby. I'm only 45 - I shouldn't be like this.
