Topic Explanation:
The forum topic titled "Why I Write the Date and Time on My Bag" discusses the practice of marking ostomy bags with the date and time of when they were last changed. The original poster explains that they use this method to keep track of when the bag was last replaced, especially since it can be easy to forget or assume incorrectly about the timing of the last change. They suggest using a Sharpie or magic marker to write the date and time in a way that is readable to them but may appear upside down to others. The poster also mentions that while some people might use calendars to track changes, writing directly on the bag serves as a more immediate and personal reminder.
