glad you are okay. in the old days the docs figured you could only get permanent brain injury if you were in a coma for a while, but they know nowdays even a brief period of unconsciousness can do it.
just something to keep in mind if you find family members in a few months time saying you've changed, or find your short memory is buggered up etc. but fingers crossed all is good....
