Earlier quoted context omitted.
High Deductible Plan. Takes care of big ass expenses, steep cost in the beginning.
It's a start, but imperfect because most people with a high deductible plan will also have a health savings account (HSA). The HSA may even be required, not sure. The problem with HSAs is that although it's "your" money, it can only be spent on qualified health expenses. So there's a reduced incentive to spend carefully, because you can't use the money for anything else.
Once you reach retirement age it can be used like any Traditional IRA account, except for inability to roll it over to another IRA or do a Roth conversion, if I understand correctly.
