Is your reading comprehension that of a 5 year old? It not taken out of context its actually very clear.
"I have very short femurs, much shorter than my tibias"
"My proportions know are very poor"
What part of this do you not understand? It has nothing to do with the airline seats or them in comparison to his legs. I have no idea how you could even arrive at that.
Theres an entire discussion amongst like 4 people (including him) further down the chain discussing his tibias being longer than his femurs. So it appears that you're the only one that doesnt seem to get it.
No, I think he is right. He was referring to the plane seat and not being literal.
I did some sleuthing. Here goes.
On March 23, he says his femurs are 45cm and his tibias are 37cm. On April 16, he says he has reached 172 cm in length after 7cm lengthening from his original 165cm. So we can estimate that in the month that passed he gained roughly 3 cm. Which means on March 23, he had only lengthened about 4cm.
That means his original femurs are 41 cm and his tibias are 37 cm.
So, no, his femurs aren’t literally shorter than his tibias. I would also be willing to bet that he’s underestimating how long his femurs are. It is common for people to overestimate how long their tibias are and to underestimate how long their femurs are due to the head of the femurs being above the trachonter landmark on the hips.
He himself, in his diary, mentions not being super sure how to measure his tibias and femurs. So it is very likely he made the measuring mistakes most people make. I would guess his original tibia to femur ratio is between 0.83 - 0.90. Longer than most people’s ratio, yes, but nowhere near “femurs shorter than tibia” as you suggested.
