Yes. I used to give my old phones to my kids for entertainment. Nowadays it seems like music videos are as prevalent as mp3s, so you need a decent display as well.

A law was passed two years ago to allow certain types of OTC hearing aids. From the FDA’s website…

To increase the public’s access to hearing aids and improve hearing, the FDA established a new category of over-the-counter (OTC) hearing aids for adults 18 years of age and older with perceived mild to moderate hearing loss that went into effect on October 17, 2022.

I was eventually diagnosed with rheumatoid arthritis.

You should find a doctor who won’t ignore your symptoms.
