I'm finding out that I like The Atlantic Monthly magazine almost as much as I like The New Yorker, and that's quite a lot!

In the May 2003 issue, I found the following information:

...consider a study published this year by psychologists at the University of Texas at Austin. The findings, published in the journal Psychological Science, suggest that people who use a diverse array of pronouns have stronger immune systems, lower levels of stress, and less need to see the doctor than people who say "I" "I" "I" all the time. The study speculated that the willingness to perceive the world from many angles is a healthier outlook than solipsism. Can preposition therapy be far away? You, me, us, them: this is a form of enhancement we can all embrace.

You can find the whole article called "The Olden Mean" (When the posthuman future meets our pre-posthuman selves" here.

Now, I say, ur, rather, you need to use more pronouns when you talk about us and them, according to me, and you'll live longer and healthier!
