My Friend Tom Harris is a Pediatric Pulmonologist In North Carolina. He is participating in a Walk-a-Thon for Cystic Fibrosis. Actually, he's against CF and the damage it causes to lungs. You can donate here: http://www.cff.org/Great_Strides/dsp_DonationPage.cfm?walkid=4754&idUser=186998
By the way, if they find a cure for CF, Tom's business will suffer.
