I personally think that the Buddha had some really interesting things to say and that >his ideas about ethics are no exception (though I suspect he may have had pain >asymbolia, which totally deserves its own post soon).

Do you think he had pain asymbolia from birth or developed it over the course of his life? Also, what do you think is the importance of this?

I've been practicing vipassana meditation daily for about 3 years and over this time period I think I've developed pain asymbolia to some degree. I've felt pain asymbolia was just one aspect of a more extensive change in the nature of mental reactions to mental phenomena.
