I'm maxing out my 401K match and contributing as much as I can to my IRA. My target date funds are still for retiring at 65 but I would be surprised if by 2060 the age to qualify for Medicare and social security haven't been moved back to 70-ish in the USA. I'm a homeowner but in a state that will likely see water shortages and increased wildfires so I have a longish-term plan to get out before I lose my investment.
My plan is to make sure I retire somewhere in this country there is fresh water and hopefully some protection from food shortages. Probably near the Great Lakes.
