Yeah, long term care could be a real problem, and I’ve not looked into LTC insurance to know what that might cost.
In most cases, a paid-for house, plus $80k/year, plus a pension - that’s likely enough for many people to live a ‘reasonably free’ lifestyle. I understand that the definition of ‘reasonably free’ is perhaps quite different for you vs, say, JasKent.
One question is how to balance the risk mitigation vs not working an extra few years, if early retirement is the goal. Some would argue you can be a little more aggressive with the understanding that a) you may not completely retire and therefore may have some income in retirement, b) if you set a pretty liberal goal for assets and something goes south, you could curb spending for a year or so.
