One of our sons had a physical for employment purposes.
In getting his results, he was told about how his numbers were "below average"... like, at the normal/ideal place, but the doc kept saying "most people your age (25?!?!!) have higher values than this"... like, his blood glucose level, for instance. He scored a 77 (which is ideal), and was told that "Average is 130 to 160" . ummm.. WTF?!!?!
Same with BP. His is about 105/60. Very, very ideal. Doc was disappointed, as "Average is 130/90". um, no, it isn't, not for his age... about 115/80 is more like it for a 25 yr old male.
