I have had mine since 1985 so I am over the 30 year mark. I just turned 50 a few months back and have had a great run so far with very few issues. In general I have 3-6 BM per day and really have had few issues at night. A recent issue with pouchitis has my attention but am hopeful I can move past this as well and look forward to another 30. I try and focus on looking out the front window and not the rear view mirror.
