Fine, how about someone who has little or no social life but derives joy from playing video games and other solitary pursuits, and also gets enough exercise (or at least as much as the average person who has good relationships)? I suspect there are some people on this forum who are like that, and more people who might become that if they thought it was the right idea.

Edit: The point is that the title implies that you'd get the significant health benefits just by experiencing joy, but the article says that you need good social relationships, so, if we believed the article, the title would misdirect people.
