We're all in agreement that yellow leaves don't make us bad plant parents right?
If not, we should be. It's perfectly fine for older leaves to yellow, no one and no plant is perfect! Just let that sucker return its nutrients back to the rest of the plant and chop it when the time comes.
Do you have a plant that seems more prone to yellow leaves than others? Do you have any plants that seem to love you and be yellow-proof?
