Clive Mitchell is a wonderful YT creator. He's a good instructor (electronics/electrical, usually), and he has a wacky sense of humor. Go check out his Fanny Flambeau video. If you're dealing with Alzheimers in a family member, check out his video on that; it's serious and it is super informative.
His brother Ralph ("Ralfy") runs a great YT channel on the finer (and not so finer) points of distilled spirits.
