Thanks, Thelma! I would have never thought of it myself, but now the sound theory seems much more logical than the electric one.
Noise is one of the things that can trigger my most murderous instincts now. Loud, inconsiderate people just don't know how close they are to being clobbered! My old convivial self is turning into a crabby oddball, because I refuse to go to noisy restaurants, to those Cineplex all-round extreme noise movie theaters, and like Birte, I prefer absolute quiet.

The only loud sounds I still enjoy is playing the music I like while driving. I sing along as loud as I can to keep my vocal chords in shape and do some decent breathing.

And now that I think of it...maybe the DBS surgery of the future should be totally revamped and instead of electrodes we should consider getting transistor radios installed!!
