Certain female college athletes, such as swimmers, divers and runners, have
lower bone density than other athletes, a new study finds.
Um, ok. So, is there no possibility that certain body types simply have greater/lesser bone density naturally and that this is not a result of the activity, but that the activities chosen are a result of a certain body type? Could it be that someone with a certain physiology is a natural fit for certain sports for reasons that can be narrowed down to a molecular level? Why is that not a consideration?
I mean, clearly there are different body types for different types of athletic pursuits. I have noticed that there's not a lot of crossover between the ballerina- and weightlifter-groups of women, ya know? I don't think this is merely an accident, but more a matter of people being drawn to physical activity that feels natural and enjoyable to them.
Yes, yes, I understand there has to be a mean average by which everyone is measured, but perhaps there should be accounting for variables like genetics and environment. I think this is probably not all that different than the case of a man who smokes a pack a day and eats bacon & eggs every morning and lives to be a hundred, while some other poor sap succumbs to lung cancer at the age of 45. It's a crap-shoot, baby.
I'm sick of hearing that some scientist has declared the last-word final understanding of a thing or a principle. After all, it was less than 40 years ago that the well-intentioned folks at Sierra Club prevented small managed burn-offs in our forest systems that have resulted in the catastrophic fires that have plagued the west and southwest for the past decade. Oh, and in the 60s and 70s, they knew all there was to know. They said so.
That's why we should believe everything scientists say about global warming, too. *smirk*
Ignorance may be bliss, but arrogance and ignorance can be deadly.
