I will agree to most of this statement except the part of youth sports. I work directly with youth sports through out the year. Football, Baseball, Basketball, Softball, Soccer, and Cheerleading. The kids participating in these sports grow every year. At least in Madison and Rankin counties.
I don't think he's referring to one general locale, where it may be growing in one particular region, as opposed to the numbers dropping like a rock in maybe other regions and states.
It's all true though. We as a society (mankind in general, not just Americans) have become somewhat dependent on technology. Instead of pedalling a bicycle, they are motorized now. Instead of walking in your shoes, they now come with wheels....
And about allergies, this so-called "allergy" to the sun - skin cancer exists because we're warned not to go out into the sun, so we stay indoors. And then when we do go outside, we're putting on sunblock. Most of our body's natural Vitamin D production comes from the sun.
Damn, I need to go renew my fishing license...
