I rolled fingerprints for a couple of years at a friend’s CCW (concealed carry) classes. The prints do seem to go away with old age, but the worst were people who shuffled paper all day (accountants, especially). After that came drywall and concrete workers.

I can confirm your experience. The hardest people to get prints from are little old ladies who work in their gardens.

I recently got my CCW for Florida, my first prints did not work so had to go for a second set, sent them in, still no luck. (Could not be read)

They issued the CCW anyway after the second failure.
I guess I am one of those little old ladies who works in my garden so much.

When our neighbor’s kids were teens, they had to be fingerprinted and they were very difficult to “read”. They were done over and over.. reason was they belonged to a swim team and worked as life guards part time. I guess all that time spent in chlorinated water made the prints less likely to be seen or printed successfully.
