>A reminder that you cannot simply retire FROM something (work, commuting, etc) but must retire TO something (hobbies, social life, second career, volunteering, etc).
Yeah, my guess is that someone retiring early to pursue their hobbies and interests is going to be much better off than a blue collar worker made redundant or disabled in his 50's. I always see these sort of studies used to slam the idea of FIRE, but I very much have my doubts that these findings apply equally to everyone.
Retiring TO something is important, but ideally it needs to involve a lot of in-person socializing, which many hobbies do not have. Golfing, for example, is pretty much the platonic ideal of a hobby that involves both socialization and old-person-friendly exercise.
