Thats why I'd work out with my friends beforehand that I would blink 4 or 5 times and then stop, the last guy to try this just said count the blinks and he got to 11 so 4 or 5 should be doable and should also help argue that I was consious rather then just blinking due to dying muscle spasms.
Everything. WHat happens to the body. what a coroner does. How a forensic scientist can tell how long you have been dead. burial ceremonies. what sense lasts the longest in a dying person- the hearing so don't say anything bad!
Cremations, motuary practices. How long it takes maggots to eat you. Necrophilia. Mummies,
The basics.
