Is it possible to avoid bitterness in the end years? If you live to 87, and haven’t had to work another day in your life since the day you retired, and you attended Mass since you were a kid, and your daughter married a good man, what is there to be bitter about?
What if you neglected regular exercise, say simply walking? Could that be a devastating blow?
What if you never verbally told the people you love the most that you love them? Could that do it?
