Very simple: Bruce seems to have a sense of humor about it all, and comes across, oh 250x more likable and down-to-earth than the perpetually grizzled, sour-puss Ford.
Bruce is 52. Ford is 87 or something.

kidding...Ford is about 65 or so (he just looks 87). Willis, on the other hand, looks like he's 42. And that's why he's my hero. He's defying nature and physics.
