LOL. What athlete has “changed the world”? I think that because we cannot operationally define what a “world changer” is, we cannot easily measure it. Personally, I wouldn’t put Ghandi or MLK in the same class as Brangelina (who are working to clean up NOLA). And I suspect many of us have people in our fields who we think have made a significant impact on others. By the way pafather, your link doesn’t seem to work.</p>
