Well Sue,

I attended an Alexander workshop over several weeks, and found it covered most of the ground already covered in Martial Arts (and theatre) I have done.

To perform well as a 'fighter' you actually have to be relaxed, not tense, and the more relaxed the muscles are, the more control and speed you have.

The various Martial Arts stuff was just a fun side thing - but I was involved with SCA Heavy Fighting for some years.

One of the 'easy' things about being an Interdisciplinarian, is that you keep on covering much of the same ground from different angles and emphasis. Just like being a Multiinstrumentalist.... :-)
