I’d rather work twice as many hours per year for half as many years. It’s not that one choice is obviously dominant over the other across all people.
And for the controversial part: The above is why I think it's insane to, for example, take 1-2 years of not working, early in your 20s, to go see the world and "find yourself." Those 1-2 years, if spent earning, could mean retiring an extra 3-6 years earlier.
If you finish uni and take 1-2yrs off, that puts you wayyy behind someone who goes straight into a job. If you take 1-2yrs off your knowledge won't be fresh and you'll not really be a new grad anymore.
Besides health there's a lot of reasons why being certain about doing something now might be preferable to putting it off for 10+ years.
