A yoga teacher told the class once that some exercises will make feet bigger/longer and warned the women, as some women do not like big feet lol... Yoga and stretching have an impact on bones.
Another thing I read, astronauts after months in space can loose so much bone mass that some of them were unable to walk.
Gravity and exercising is vital for your bones. If you don't use it, you'll loose it.
You should see the positive side of not being too tall: short/small people live longer, same with dogs: Big danes have very short lives, for instance.
Not sure, but something to do with gravity...
My grandfather was almost 2 meter tall, died of cancer in his mid 60's, was not a smoker, not a party guy, frugal, not overweight, working a lot...
