Create a "real mode"

Minecraft has 5 games modes creative'survvial'spectator'hardcore'adventure How about a mode that makes the game slightly "realistic" torch's and candles would eventually go out. water would have to be drank. the only way to heal is with a healer villager. the damage you take from falling from a minimum height is increased. drowning takes less time lanterns would have to torch's swapped out. the only permeant light source would be Redstone lamps and glow stone. you would have stamina that gradually drains. You would take freezing damage similar to powder snow in cold areas but also heat damage in hot areas like the desert and savanna. You can only break blocks with tools except clay and sand. Breaking blocks also takes longer and so does kill mobs. swords and axes don't wear out from use instead dulls and has to sharpened at a grind stone.
