Good places to retire? Sorry-long

What is your family situation? I'm pretty happy with where I'm at, south central Missouri. Cost of living is reasonable, Springfield has about everything anyone would ever need, and there are several small town close by, where you don't have to deal with the city problems. Mostly more important to me though, my son, and his family live here. I can't even imagine leaving him, and my two grandson's. Another thing to consider, as we get older, we are more susceptible to health problems. I have known people who have retired, moved to their dream place, then had health problems, with no family close by to help. Just some things to consider.
