Lot of people cannot retire early only because of insane healthcare premiums. Throw in a preexisting condition and you're screwed. To a 50 year old with spouse with preexisting medical condition with assets generating enough cash to for living expenses (that would be me), Obamacare is a God send..... Don't let this observation take the thread in a different direction though.....
The vast majority of people cannot retire early. Some of them can retire at 65. Most cannot. That's the reality.
