i often wonder, what with the salts, acids , alkalis ect and how they affect us whether we react depending on our charge{electrically wise) and where the charge comes from, thus opening up the concept that thought is partly at least external as of the definition of the soul... i have written a bit of prose/poetry about this in my blog "Last Thing On My Mind" part 9 I think... i like playing with thoughts and words inventing new unconsidered possibilities... and would love it if you read some and gave me some feedback... all the best, robin
