Could you bear to wait eight more years for the 100%? You’ve already waited 62 years! What’s 8 more?

It’s easy to think that way in your younger years. That’s a much difficult request for people actually in their 60’s, lots of people make it to that age with broken down bodies, various illnesses/prescriptions/whatnot & probably can’t see themselves continuing to do the work thing throughout their 60’s let alone 70.

There’s also the problem of holding down a job at that age, ageism exists in a lot of industries so a lot of these people are first in line for layoffs / taking a massive pay cut from their earlier jobs to being a Walmart greeter or just being unemployed.

But sure… in theory if you manage to stay fit & healthy well into your old age & are able to hold onto your normal job then sure working into your 70’s or more could be plausible.
