You do realize that our body keeps going via chemical processes? Genetics can cause insufficient absorption of certain nutrients, and given the long term consequences of chronic deficiencies, testing may not be such a bad idea after all. Also, knowing your blood work means that you won't be stuffing yourself with pills you don't need.
That's what I'm talking about :) 99% of people will go on to live just fine without knowing their precise blood levels. "Preventive medicine" is not considered to be advantageous, usually the anxiety and stress outweights any benefits unless you end up being the 0.1% and finding a serious condition that didn't raise any alarms in your body.
