Why am I so handsome is the question I (and probably everyone around me) have decided to address. But, alas, the answer to such a question is beyond mortal grasp.

I was wondering about why insulator regions can have 2 functions and not be designated as different components. Perhaps this is just because both roles have effects that could be loosely described as insulatory. Are there instances where both of the functions result from a single segment? And if so how would it perform functions when they are both so very different. Also, I realize they would have to perform the functions at separate times, but still, I don’t immediately realize how both could be achieved without a complex mechanism.
