I will be 76 next Saturday, so yes, age is a factor.  Not having the best bladder control for years combined with a prostatectomy, removal of a large bladder diverticula, heart failure, and now pretty severe spinal stenosis and peripheral neuropathy I continue to manage by wearing diapers.  Some days I could possibly get by without them, but can't predict when those days will be.  I guess I have accepted my new normal...prepare for the worse, and hope for the best.
