While people may be living longer their mental acuity and energy levels plummet as they age. A 70 year old would not he able to handle the attention to detail most jobs 35 year olds are working. I see people starting to check out in their late 40s and phone it in.
Idk what kind of roles you are expecting a 74 year old to work because if we put all those 70 year olds into the work force, what are they doing?
Finance? Working long hours on their feet in a busy kitchen? Doing excel spreadsheets?
What are they doing cuz I only see them as Walmart greeters
Btw if about finances, some are working and even does have business or shares (%) in some company.
Board members, sr level bookkeeping etc...also financial advisors etc too happens.
Some from these old are using not only just excel, also MATLAB type stuff etc... specialized programms for accountants, traders etc.
Ofc not all can do this...however I do know such ppl, had worked with such stuff and we are using 60+ y.o accountant today, for bookkeeping too. Why to experiment if he is doing stuff 10+ years without problems for us...experiment?why.

There ofc it depends...but if he had used computers a lot since 1990 ies....and really even with just excel...
Excel is nightmare for accounting tasks.... torture....
It is beautiful tool for damn a lot of other, even very serious tasks.
Accounting .... there since 1990 ies more and more are used specialized programs ...for warehouses too.
However if someone had used excel some years for this...then he will be happy and quickly adapt to use specialized program.
As for Excel actually usually young students does not know even 10% from options and tools and for a reason.
If printed on A4 format pages...full tuts are approx >4 lbs...in weight.
I use excel too and had used since late 1990 ies... I do have some 3 or 5 books about this and downloaded tuts etc...
Yes, I don't have problem to use also macros etc..and still I sometimes lurk in Q/A, book or some printed pages... net ofc too.
As if about tools or programs, doesn't matter are you 20 y.o or 60 y.o and what kind of paper you have...
Of you for example have program for some task version x.s.xx. and will have now to use x.s.s.xxx ...to move to this with all data etc.
Sometimes it is press button. Sometimes it might be very hard task....
Like if you are even maybe programmer, tools does have different versions too. Compilators too. Libs etc are..mmhmm.
Yes, even very experienced specialists always are learning something and checking ....IF¿
Earlier was for example hype that if you will be programmer etc then easy money forewer.
And then when students get to see some 50+ y.o wealthy senior level specialist telling them : it is...always learning. Otherwise.....
