I've been car free for over two years now and doing more and more cycling. So far this spring my cycling has increased to new heights. I did a half century last week and followed it up on the weekend with cargo hauling and shopping of about 16 miles total, including hauling mass amounts back from Costco. I no longer need to dismount for most hills, and I can keep a steady if not exactly speedy pace in headwind. In the mean time my resting blood pressure has fallen back into high normal range and is still decreasing, resting heart rate has dropped and overall health improved. Joint and back pain has also gradually reduced. I have a game left knee but as a good ortho advised me the more cycling I've done, the more muscles have developed to compensate for the weakness of the joint.
At the same time, my weight has been going down only gradually as muscle mass increases and fat decreases. All well and good, except that according to the sanctified chart I am still over 48 BMI and about to die! I would be a candidate for emergency surgery! I've also been rejected as a bone marrow donor because of this number, even though my overall health is excellent for a 39 year old and I can easily pass any treadmill EKG or other test they want to run on my innards.
Now I grant that I am something of a monsterous mutant. I"m quite thin at 200-210. That's what I weighed in my prime of fitness in my early 20's. The fact is they simply did not make humans like me in the 1830's when that chart was devised. Thanks to modern food production and nutrition, every part of me is on a larger scale, from feet to hat size, than a person of that era. I've seen their clothes and read the military reports from the era describing in cold numbers the massively under-nourished European population. I'm also the product of genetic combinations that were unknown at the time, leaving me with somewhat thick stumpy legs and an extra-long torso. BMI takes no account of ANY of this.
But that said, I'm far from the only one who's reality diverges sharply from the archaic BMI measurements. I would say that the error is harmless except that in my case, if I chose, it would lead to a dangerous and totally unnecessary surgery. Further, it may have already cost lives by denying my rare tissue type to those in need of marrow.
What can we do to stop this idiocy? Short of kicking doctors who use the charts in the groin so hard they'll never have kids.
