I think that's natural and reasonable. I'm certainly less tolerant of drains on my time as I get older. I can imagine that, at 85, I would be making a lot of calculations about ROI on my time.
Edit: For those seeing an argument in my statement above re: forcing people to use technology or forcing business to make an accommodation for people who don't want to use technology: I am not making a statement either way. I'm simply saying it seems logical and reasonable, natural even, to value your time more when you have less of it.
But if you don't want to, then you shouldn't be expecting other people to accomodate you.
