Is it the western worlds taboo on the subject of death and dying that causes so many problems?
Partly, we Westerners are bad at dealing with death but the fact that we seem to be supposed to prefer death to severe sickness and disability suggests that we are even worse at dealing with those. Yes everyone is going to die; we have therefore got to make the best of what is always a very short and precious life. We cannot make everyone well or able but we could do a lot more to make life viable for people who have an illness or disability.
