Good hearing can subsequently deteriorate. At one time one could hear everything clearly, later on all sorts of sounds become very soft. It is like some kind of wind gets into one ear and goes out of the other. Good eyesight weakens and we cannot see as clearly as before. Sometimes we look at one person but see two.
Delicious food becomes tasteless.
Wherever we used to go and enjoy ourselves, we have no strength for an outing anymore. This is the way things are. If there is birth, everyone will have to accept this and consider that nothing can put an end to it. Do not grieve, just accept it. Contemplate the arising of suffering and try to understand and see through the whole process with sharp awareness.
