You learn something new every day

...whether you like it or not. Today I learned that your arm span is usually shorter than your length, meaning if you elevate your arms out from your body in a 90° angle it's often shorter than your length. I learned this today when borrowing a guys jacket and the sleeves went down to my knees. What he didn't tell me was if fingers count, because if they do my span is 1.68 compared to my height 1.65, i.e. long arms. But what if cannot count the fingers? I have to find out. But not now.
