> I am told that the older you are, the harder it is to adapt to hearing aids.
I started wearing hearing aides in my mid 50s and had no issues, and the positive effect on my hearing was immediately obvious (night and day, in fact). However, I think if you were much older and losing manual dexterity and visual acuity there might be problems - e.g. they can be quite fiddly to put in and clean on a daily basis. Cleaning the tube that goes in your ear is like threading a large needle with a fat wire. Steady fingers and corrected eyesight helps.
