Ah old age

So I’m stooping down to look under my sink and see if the leak has been fixed. I’m shinning my flashlight at the approximate location of where the leak had been and hear a periodic drip but can’t see it. Then I realize the sound isn’t a drip but is coming from my knees and ankles. It has nothing to do with the drip and everything to do with me being old and creaking more than ever.
