I agree with previous comments that the height growing stage of life may have passed. However, there were those funny stretching tables they used in dungeons during medieval Europe history, just kidding.
Seriously, jujanester, why 3 inches. Are you trying to be taller than someone else? A glance tells me your smile is pretty tall in far off lands of saddness. Height may only be subjective. Seems to me there are a stories like David & Goliath, Jack & the Bean Stalk, and Gulliver's Travels alluding to this.
I think your two hubs are wonderful and are a catalysts to achieving great heights. And you have figured out how to ask a question here, so you are much taller than me on that, since I don't know.
Oh, yeah, take a look at all the famous women race car drivers, they aren't really tall at all. Go to the library and pick up Danica Patrick's autobiography - she isn't 5'3" either.
remember to have fun, fun, fun
