Do your dominant limbs break down faster than your other limbs? 

As in, does the constant wear and tear of using your dominant limb mean it eventually gets weaker or easier to break?

To the contrary, your dominant limbs are less suceptable to incidental damage.  Your muscles and their supporting structures (including bones) respond to constant conditioning.  It may seem like your dominant apendage is at greater risk, but this is because it is being used more frequently and is more likely to be subjected to extreme behvaior by you. If we are just talking about normal everyday activity, the coniditioned appendages will be unquestioningly more resiliant than an appendage you have allowed to atrophy.

Consider astronauts.  When they return from the space station after and extended stay there is a noticable degredation in their bone and muscle density.  They are in fact made weaker and their bones are more likely to break as a result.
