when you over 50 years old,studying English for
a few decades,and are retired to home without
doing nothing,what is the use of English?

Well,if you were a 50 years old or more,you would become a grandfather,and you have to realize that you have lot of grandchildren,you can teach them english.Why not do it?
What is more,there is an old saying goes:"Live and learn"-----You are never too old to learn english.(活到老,学到老).
