H1N1 Or Swine Flu Question

I was pondering this as I walked the dog this morning. The swine flu seems to be attacking primarily young people; kids, teens and 20 somethings. I wonder if this isn't a product of the "clean generation". Parents have so protected the children of this generation. They've kept them wrapped in antibacterial soaps, wipes, creams. They keep them from running, playing and getting dirty. They get antibiotic's prescribed for the sniffles. In short, they've kept their kids too protected. I wonder if this is not a reason why seemingly healthy young people are being so adversely effected by this. Just a thought.
