The pioneers conducted a big bible study in a nursing home and without exception all of them were drooling or sleeping.
And the nursing home residents were even worse! (Boom boom!)
I recently saw a video of people getting baptized at one of the big assemblies at NY in the mid 50’s – virtually all young adults in their 20s or 30s , mostly married couples.
I honestly can’t remember the last time a reasonably competent adult who hadn’t had some previous family connection with “the truth” was baptized. We had a Q&A on the monthly bible study offer – not one study had been started , so the brother had to read a few experiences out of the Yearbook.
The few who do occasionally come along are the rejects of society who are grateful that someone shows an interest in them. Even so , because their domestic lives are so chaotic , it can be very difficult for them to get into the routine of meetings & ministry necessary for them to reach baptism.
