lol, this friend.......no offense, but does he keep proper hygeine ...washing, cleaning his teeth properly? Im sure you've already asked that...failing that, maybe there is something amiss internally causing it and could be permeating everything, like coming out of his pores, in the sweat etc. I don't know if cavitations would be the cause, but hey, anything is possible.

Im sure that you'd be more up on cavitations than I would Elvis. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
