We're going to have to extend working age and think about career changes there's no other way about it. No matter what else we do I think we're in for that.
People used to retired and die 2 years later.
Not only are we living a lot longer, we're assuming massive medical expenses to the point where 80% of your life 'healthcare' will be well after you retire.
Social Security economics - even socialized medicine - are not going to fix this because the expense is still there.
We're going to have to 'do something' past age 62 both to offset costs, but frankly, it'll probably keep us saner and healthier.
