So all along I thought I was 5'6.5" because whenever I measured myself, I got 67.75 inches, then converted to feet, it's 5.65. I stupidly always thought it's equivalent to 5 feet and 6 1/2 inches.
Today, it's a slow Sunday, and I thought of measuring our heights. I got 67.75, The Guru got 70 inches. Then he converted them to feet and inches and apparently, I'm 5'7" 3/4 and he's 5'10".
Which means I've been measuring my BMI wrongly all these years. And since females get 5lbs for every inch above 5ft (male get 6 lbs/inch) based on the ideal body weight chart, it means I'm 5 pounds closer to my goal weight (a long way to go, but still) than I thought I was.
Just sharing. It's like finding money hidden somewhere which I've already forgotten about. :P
