This sounds ugly and calloused, but going after eighty-year-olds makes no sense. Unless you're pushing age-specific services, don't bother focusing on 44+ -- most marketers don't. Not only are the spending habits all wrong, but by the time 80-yr-olds adopt bitcoin, what will they buy? A casket, a grave plot or an all-expense trip to a crematorium?
Let's keep focused on realistic goals.
Actually Bitcoin makes a lot more sense to someone who was brought up using cash and experienced the great depression and bank runs of the 1930s even as a child than every other form of electronic money today. As for what an 80 year old can do with Bitcoin here is an idea from a 90 year old to fund one's retirement:
In 1965, aged 90 years and with no heirs, Calment signed a deal to sell her former apartment to lawyer André-François Raffray, on a contingency contract. Raffray, then aged 47 years, agreed to pay her a monthly sum of 2,500 francs until she died. Raffray ended up paying Calment the equivalent of more than $180,000, which was more than double the apartment's value. After Raffray's death from cancer at the age of 77, in 1995, his widow continued the payments until Calment's death.[2] During all these years, Calment used to say to them that she "competed with Methuselah".[9]

a) No money
b) No computer.
c) Expected lifespan < 2 yrs.
Anecdotal evidence (the story you posted), while proving that X is possible, doesn't imply that X is likely. While there may be people who live to be 150, it's foolish to gear your product to 150-yr-olds if you're in it for money & not just lulz.
As far as remembering bank runs as a child? If you're old enough to remember those, you're old enough to *not remember anything else*. I'm sorry, but if i'm over 80, i prefer to be mercifully put down over having to trade in bitcoin on this forum
Just explaining why PayPal and Debit/Credit Cards suck. Fortunately, nowadays there is Bitcoin!
