The District Attorneyâs office presents evidence that would be admissible at trial, and the grand jurors vote to issue a âtrue billâ if they believe the evidence, if unexplained or uncontroverted, would justify a guilty finding at trial. Grand jury service is for approximately one month.
If you weigh 200 pounds and are about 6 foot tall, your skeleton would weigh about 30 pounds. Adult human skeleton weighs around 20 lbs, and contains 206 bones (I'm not sure if the later includes the tiny 'anvil' bones in the ear).
I'd be a little wary of the 11 pounds estimate. For example Human head article on Wikipedia puts that figure down to 5-11 lbs. But this is quite irrelevant since in many cultures you see people (especially women) carrying great loads atop their heads either for cultural reasons.
