Would you rather burn to death or be buried alive?
Burn to death. It would hurt like Hell but I wouldn't be trapped underground, clawing at the dirt with my hands, feeling my lungs struggle to hold on to every last molecule of oxygen - I would feel the heat on my skin in fire; feel the flames licking at my flesh and melt it from my bones, but being buried alive and suffering for longer; feeling each breath get harder, my heart beat quicker, taste dirt in my mouth in the utter, hopeless darkness would suck more.
