I like where your heads at, here's the study with a solid summary up front: https://www.thelancet.com/action/showPdf?pii=S2666-7568%2823%2900232-5

It has a great sample (nearly 10,000 folks with a mean age of 48.6 and having a standard deviation of 18.1) and the findings fortified previous studies. Biggest thing is the fact 12.7% of those with hearing aids rock em, and rocking em is the defining feature in the study. Even when non-consistent users were grouped together with those never having used a hearing aid, the consistent group lived longer. This alone shows going to the doc isn't as impactful as you might to think.

Edit: The work also states more research is required, but the data is looking like something big would have to arise to disprove the construct!
