Neck straps are more interesting.
Actually, wearing one so that it passes behind the neck with the camera hanging down the front of you is not any safer or more comfortable.
Once you have your first heart attack you discover more interesting things about your neck as, for examle, the two arteries that run down both the sides, right where the strap likes to press itself. A little too much time so strapped up, and you can feel yourself faint quite away: almost as in a ladies' magazine article, but without the thrill.
Best to keep cameras in a case, the case left at home or in the studio. Or, in extremis, have it carried by/in the tender care of someone much younger and ignorant of the dangers that lurk therein.
As for the value of pictures - depends how much money and/or sense one has. Oh, taste: forgot about that. Let's just look at paintings, then.
