Here's the Guardian comment:
In praise of ... Dustin Hoffman
The star saved a jogger in Hyde Park who had collapsed with heart problems
Here is the paradox: Dustin Hoffman makes his name playing anti-heroes (think Ratso Rizzo in Midnight Cowboy, or David Sumner in Straw Dogs), yet this week's reports that he saved a jogger's life are immediately convincing.
and here's the response, from someone called Yaffle:
There are lots of similarly amazing paradoxes in the world. Daniel Day-Lewis is famous for playing a man who wrote using his left foot, yet in real life, he writes using his hands in a way that witnesses have described as "convincing". And I hear that although Russell Crowe played a Roman gladiator who died, in real life, he's Australian, and an actor, and not dead. He achieves this triple paradox in a manner so convincing that it makes his movies almost seem like fiction.
Dustin Hoffman is of course also famous for following the Ulaca fitness regime.
