5 years isn't a reasonable timespan. Compounding over the course of a 35 year career, earning a modest wage, will fund a comfortable 20 year retirement. If that's "bullshit" for most people then too bad. Good things come to those who wait etc.

A 20 year retirement on the back of 35 years of working means dying before you're 80?

Given current life expectancy, and particularly if you find a life partner, the chances of at least one of you surviving through at least 85 are pretty high (like above 60% for the US).

		I assumed that a "real" career and substantial savings, after paying off debt, begin at age 30. And the 20 year retirement was me being conservative. In truth, saving only 20% of your take-home for 35 years will be more than enough for 40 years.
