As long as you don't have kids :-) Or perhaps you're counting on them to pay for their own education. But yes, if you save your money and budget well, retirement is simply an 'if condition' rather than a 'when.'

That said, he doesn't cover variable costs as much as he should (rent changes, taxes, sudden medical issue) this is something that fixed income folks have lived with so there is a lot of stuff out there for managing those events as well.
