***** NOT A TEACHER *****
(1) Bob Smith has already given you some terms used in the States.
(2) I just wanted to add a few points:
(a) Most Americans do not like the word "old." ("Everyone wants to live a long
time, but nobody wants to become old.") Neither do they like "elderly" very much.
They prefer to be called seniors. Or even better:
active seniors!
(i) So the word "old" does not appear in any official terms.
(3) I agree that
"retirement community" is one of the more popular terms.
But many retirement communities might have happier official names.
(a) Here in the United States, one of the more popular retirement communities is called
"Sun City." It has "cities" in different parts of the country.
(4) Please remember that -- as in all countries -- everything depends on how
much money you have and on your physical condition.
(a) "Sun City"
ain't cheap!
(b) "Assisted living" (mentioned by Bob Smith) is for people who need help to handle
everyday routines.
(c) "Nursing home" is sometimes a kind term for places where the residents are very old and very sick.
(5) I have read that what to do with us old folks is becoming a bigger and bigger problem in many countries.
