Simon duh skeleton

1. Simon’s bones and theoretical height:
Bone | Length of bone | Theoretical height
Humerus | 27.5cm | 150.225cm
Radius | 22.0cm | 157.887cm
Femur | 38.5cm | 153.685cm
Tibia | 36.5cm | 165.387cm
2. My bones and theoretical height:
Bone | Length of bone | Theoretical height
Humerus | 26.0cm | 145.884cm
Radius | 24.5cm | 166.0645cm
Femur | 40.5cm | 157.445cm
Tibia | 38.0cm | 168.951cm
Actual height: 163.0 cm
3. Possible reasons for discrepancies
Human error I guess. The way we measured the stuff is not really very accurate. Also the instruments used may not offer the most accurate answers as they are not as precise enough for the job.
4. Golden Ratio thing!
In mathematics and the arts, two quantities are in the golden ratio if the ratio of the sum of the quantities to the larger quantity is equal to the ratio of the larger quantity to the smaller one. The golden ratio is an irrational mathematical constant, approximately 1.61803398874989. Other names frequently used for the golden ratio are the golden section and golden mean. Other terms encountered include extreme and mean ratio, medial section, divine proportion, divine section, golden proportion, golden cut, golden number, and mean of Phidias. In this article the golden ratio is denoted by the Greek lowercase letter phi, while its reciprocal, is denoted by the uppercase variant Phi.

My body does not fit the Golden Ratio! (This proves I'm super fat and ugly)
The Golden Ratio is 1.618. My Ratio is 1.922 (That's way off, so I'm SUPER SUPER fat and ugly) :P
5. The case of the middle aged woman:
Age of woman: 70 years old ( 2011 – 1940 – 1)
Length of tibia: 33.5cm
Theoretical height: 33.5cm x 2.352 + 74.775cm = 153.567cm
Actual height after subtracting (Height decreases by 0.06cm per year after 30 years): 153.567 – (0.06 x 40) = 151.167 cm
