2 days spent asking *how* do you want to live your life in retirement?
Large part focusing on how to stay active -- pointing out that going to the gym is not going to work for most people because they get bored and quit, get involved in something that requires semi-rigorous exercise -- like bicycling, mountain hiking (strolls along the beach don't really count), canoeing, kayaking, maintaining a large garden, snowshoing, skiiing, ...
We love the out of doors and are fortunate to have mountains for hiking and backpacking just a couple of hours away. I also volunteer at the national parks working on trails when we're not in a pandemic.
Social interaction -- consider volunteering, or part-time work, or just working longer than you planned if you like your current work.
Marital interaction -- "married until death" does not mean 24/7. Spend time in separate activities and social networks too.
Where you want to live is certainly important, but consider what it might mean to lose current interactions with local friends and having to start over making new connections if you move far away.
For us, travel is important (not travel to visit relatives) -- gives us something to dream about, then start planning for, do, and then have memories of and share our experience with friends and relatives.
