What happens after death?

[Nice]

It's possible that a drug that was injected when he was at birth or something and one of the chemical compounds that can make the heartbeat and everything to be suppressed was on a in-active state.
When another compound came in contact, it simply wakes up and suppresses heartbeat and other things -- making him maybe dead.
After a prolonged time is done, it comes back to in-active state and it makes him to wake up. But then, other compounds could of merged with it and it so hard that he died.
This is just an opinion. Nothing bad was implied to anyone.
