Those Hanson boys are such do-gooders! They were in the Thirty Mile Zone today on a very special mission -- to fight poverty and HIV/AIDS in Africa. They are walking a mile -- in West Hollywood -- to help raise awareness, which will then be followed by a performance.

Eldest brother Isaac showed high spirits when asked about his recent pulmonary embolism. He ecstatically proclaimed that he's "feeling really, really good." You can't keep a good boy down!
