***SNIP***

Didn't mean to imply there was, though even as large as four inches
impresses me.

Point I was hoping to make was that such extremes don't require the step
into outer space to challenge bio-engineering. Never meant that it could be
done 'off the shelf'.

I'd hoped I'd covered the 'exposure to vaccum' by suggesting bio-mechanisms
to keep the cells from exposure.

Anyway, I'll quit slugging from ignorance, now.
