Thanks for you reply Tradrockrat! However, I believe this is false information. Calcification of the shin DOES make your shin more dense, hard, and thus less likely to break. Secondly, the damage to the nerves isn't to the extreme that you describe. It may lighten up the pain somewhat, but not to the point were you can't feel your "breaking point".
And I thank you as well sir for a good debate.

I guess it's all a matter of extent of conditioning. It most certainly
can be extreme, though I'm sure it isn't always so. I agreed that the condidtioning does make it harder, but it doesn't give you armor plated shins - that's the real falsehood. I was a little simplistic in my previous post and you rightly called me on it. The shins aren't completely deadend, but they do take
substantially more punnishment when you feel less pain and you go harder for a longer time. More punnishment equals more damage, right? And what we are calling conditioning is actually controlled, systematic punnishment.
In regards to self defense, I can't imagine how having tough shins wouldn't be beneficial. Being that its the striking/blocking area for most leg techniques, it would seem only natural that it should be able to endure more stress. Of course this is just my personal opinion, but if one is only conditioned to hit padded surfaces, how can one hope to survive bone contact? When a karateka practices for board breaking, they don't practice hitting softer surfaces... they hit something comparable. Why should Muay Thai be any different?
Well I can only speak from experience - I used leg kicks extensively in my life and I never broke 'em - and I kicked like a mule

Shins already handle plenty of stress. In fact, they ARE tough already! Also, my experience in self defense involved rather short fights compared to my ring experience, so I have no problems stating that conditioned shins have no real benefit for self defense applications. They really only enable you to take more punnishment for a longer time - just not that relevant in self defense cause I don't
want to take punnishment for a long time in a real fight. That's what I'm trying to get at I guess.
And living for another 40-50 years isn't really relative as there are many Nuk Muays and krus over the age of 50 whom operate just fine without leg problems.
And I've met some who do - It does damage plain and simple. Of course fighting does damamge too - perhaps it's a cumulative effect from all that ring time? One of my training partners went the shinai route and saw definite improvement in the ring, but his shins look like crap today. Now in defense of your point he still walks fine - for now.
I guess my main point is that I just don't see a reason to do this unless you wish to fight professionally. JMHO.
