This misconception is why I and many others prefer the precise wording: gaining healthy(ish) years.
You don’t die of ‘old age’. You die of disease(s), which become more and more likely as you accrue damage throughout your life. You can’t really extend the period someone stays alive with end stage dementia or cancer. If anything, you can only prevent, halt, or slow the development of the diseases. And that’s what’s meant by longevity/extending life.
Granted, you’ll still accumulate non fatal issues. But I’d argue you can lead a meaningful life with knee pain and far sightedness.
My high school IT teacher said this outright. He was a FOSS guy, but he said employers will expect MS Office, so we’re going to be learning that.
Funnily enough proprietary software is frowned upon in my professional domain. Im not mad though, the excel commands and whatnot still work in libre office spreadsheets.
Unrelatedly, doing statistics in a spreadsheet program sounds like absolute hell.
