That's kind of impressive.

Taking these two science facts and adding the anecdotal "I kicked a tree and over time it bothered me less...it must have thickened my bones, deadened by nerves, it can't be that I callused my skin, learned the right angles to hit at and/or got used to the pain" adds up to "Man I train so hard I shatter my bones anew each day so they re-heal thicker"
Yes, you can make practical increases in bone density. The best gains are made by consuming adequate minerals and exercising. It is very likely the constant exercise rather then a particular practice that thickens the bones of martial artists.
The benefits of impact conditioning are dubious. Cultures that engage in the practice seem to produce good fighters, but so do cultures that don't. So the function of the training (thickening the bone) is unverified, and the relationship of the training, if assumed to be valid, to combat is also dubious. The training does have potential for bodily harm and loss of valuable training time that could improve the body more efficiently if spent differently.
Also, while I think it is really cool that you can afford to train in thailand, and really cool as well that where ever I go in the world, there are Australians there to translate for me, anybody can pay to train in thailand - it doesn't make **** into icecream just to breathe the air there.
I broke a stack of twelve hymen.
Yes, if you don't really understand breaking. If you do, you are more impressed by single breaks and stacked bricks with no spacers.

Open up wikipedia and read up on BONE, specifically bone remodelling.
Bones will get thicker as a result of exercise, getting stronger as a demand of the exercise.
"Repeated stress, such as weight-bearing exercise or bone healing, results in the bone thickening at the points of maximum stress (Wolff's law). It has been hypothesized that this is a result of bone's piezoelectric properties, which cause bone to generate small electrical potentials under stress"
Well, the second part of that is just hypothesis, the first part is clear. Exercise toughens bone. It does not say what type of exercise, but i would imagine that shin kicking bamboo stalks until everyone you know calls you Jean Claude would thicken the bone a bit...and you may be able to do more damage with it.
Doing more damage than a skilled stonemason with his trusty 12 pound sledge on full swing is another story. Instead of striking bricks they should have them strike a pressure plate that shows PSI of the strike and then you would see....
Physics is proven. Force = mass x acceleration. A sledgehammer does not flex either like the bones and cartilage of the guys leg or arm that is striking. This flex does absorb SOME of the impact of the strike.
However, a sledgehammer is not exactly a reasonable option for self defense. While it would be convenient to smash someone with a sledgehammer, I doubt anyone is going to stay still long enough to get a good swing in on them...especially as slow as they are.
This is why I still recommend a nice .45 smith and wesson with extra clips for the odd chance that 60 viking warriors are coming after you for your wallet like in those capital one commercials.
Last time I tried to break through a 2 inch patio block my radius bone almost protruded out of my palm. But that was an actual construction cinder block. I don't break anymore.

You also have to know the proper technique, even if you are performing a trick. That is why, in another thread, I say it is also a skill.
Kind of like lock picking in magic tricks. Lock picking is a skill used to perform a trick.
