Interesting fact...they actually have far more bones than an adult human, they merge as they grow older into the standard 206 from the textbooks. Anyway....just think for consistency in your definition of abilities you have to ramp up during childhood/teen years in addition to ramp down as they get older.
Interesting that the average individual on your graph lives to 78, and you say the overweight person lives longer....but as far as I can tell the overweight person IS the average...but maybe I'm just being picky  .
p.s. I am an engineer as well, and love your graphs |
ACK!
You know what I was thinking as I was writing this and uploading the graphs? EXACTLY the "newborn oversight"... I did the graphs while transferring some files at work (this took longer
), and didn't really have time to fix them. Probably shouldn't have found the time to do them in the first place. LOL.
As to the average part... 78 was chosen because the "average" life expectancy in the US is currently 78, and I just picked a number to put there. That said, you did bring up a point that I didn't think about....
Per Dream's recent links to studies... The studies (they didn't really study anything, more data mine and sort, but still) measure "risk of death" normalized to "normal weight per BMI in some 100's of thousands of deaths. Average BMI having a risk of death of 1.0, overweight people had a 0.94 and obese class 1 had a 0.95 (less risk). class 2 and class 3 obesity carried a 1.24 or so risk (ACK!). Oddly enough, I do not recall seeing any underweight parts of the study... though those may be difficult to find.
SO..... I had made the connection, "average life span" is that of the average person, and they have "normal BMI"... but that may be wrong. The average person is currently overweight... therefore, the overweight/obese1 line should go to 78, and the "fit person/average weight" (green) line should go to 72.
