Growing taller

[Chin-Chin]

Not to mention that the posture really matters.

Just by standing straight, some people gain half an inch!

Bad posture is of course exacerbated with old age, making some people shrink prematurely.

I remember reading something about a guy (I think the guy who invented them) that used gravity boots regularly to hang up side down. From some late age to some later age he gained a small amount of height when most poeple lose height in those years.
