Have you lost weight between then and now?
Were you under 25 two decades years ago?
Probably the weight loss. Same thing happened to me when I took up running and started losing weight. Gained 1 cm or two. Though, I'm not sure if the body is un-squeezing itself or it's simply having a straighter back that helps with the height increase.
I was between 18 and 20 and measured and measured and measured... I had been joining the army around that time, and since I applied for officer career, I enjoyed the full treatment. I think I had my height measured about a dozen times alone until I was 25. It never exceeded 185 until I was 30.
And I lost 17 kg last year in a few months...
Nah, the other 7 billion of us just got together and made significant changes to the definitions of the meter and kilogram without telling you, just to play a practical joke on you, personally (or, given the effort involved, an impractical joke).
Reminds me of the ultrasonic rodent repellents which are popular around here in all kinds of malls and shops. They are supposed to be inaudible to humans, but i happen to have an abnormal left ear which can hear up to 19KHz or so. I can see why it works on rodents - the skull-drilling intermittent whine they give out is pretty darn annoying.One of the farmers nearby set up a bird repeller gas cannon
