For travel? There are plenty of digital nomads out there travelling the world right now for way more than 80 days and not waiting for retirement to do so. I've even met multi-year backpackers who do it on very stretched dollars and small incomes, but because they travel slow they can make it work. Retirement isn't guaranteed either way, so if travel is something people want to do they have to make it fit into their life choices (also it's probably far easier to enjoy and spend less on when in good health, but im saying that as someone who budget travels and can easily shrug off inconveniences while traveling). Also, theres no need to wait on other people to travel, solo travel is pretty damn relaxing.
