Moving to a "warm climate" versus staying put in a colder one ?

6. I think that it depends on the person.

Some people will exercise if the weather is good enough, and in a snowy, cold area, they will just stay in the house. And cold weather can cause some problems like arthritis to be much worse, so being away from the cold helps them be more comfortable. And there is also the problem with always being cold that some of us old people have. So if you are cold at 70 degrees, you are unbearably cold at 10 degrees. And if you have ice and snow a lot of the winter, most older people do not feel comfortable driving, so they end up stuck in the house all winter.

However, the places that you are suggesting are extreme in the summer, which can cause a whole new set of problems.
