Right-handed lolz

I saw this headline:
Keyboard's Right-Hand Letters Make People Happier and thought, "that's because you spell LOL with your right hand." And then the article says,

The researchers found that... people had more positive feelings about words that mainly involved right-side keyboard letters. [...]

[T]he association was at its strongest in new words and abbreviations such as "LOL."

Tomorrow's post will be written entirely with my right hand.
