After you get past a certain age, you may also want some help for yourself from your children. The cost of a maid or other household help in many developing countries is low enough that you can get much much much better help there than you could possibly get from your adult kids with their own lives in the US. A really good live-in maid will run you $500 a month (a great salary for many people). They will cook all your meals three times a day, keep the house spotless, do all your laundry, run errands like buying groceries, etc. You can't find service like you can in Brazil without paying a pretty penny. The average cost of a retirement community in the US is $2750 a month, many times more expensive for probably far worse service, with one employee shared among many retired individuals.
