What will happen to my body if I die in a locked thick steel like box with no openings?

Question

Or I need not to care about my body after death?

Answer 1

It would decompose and become a soupy smelly dangerous mess.

Answer 2

try it and have someone report back to us after a year or two.

Answer 3

I wouldn't care too much about that, just live life, and when the time comes...ahh who cares you'll be dead already!
