Valuable lesson taught by Dao is aging. No one has figured out how to
stop aging. Trees rise from saplings to towering high. Then day comes when they
topple over. It is most wise to age gracefully and wisely. Most interesting how
as young offspring, we seek to grow older to satisfy dreams. Yet when older, we
often look back longingly, desperately seeking to remain young somehow. Old
saying; 'there is no fool like an old fool', but fools come in many ages. A person
who is comfortable with aging process demonstrates great wisdom.
