What’s the MOST unrealistic thing in TLD?

Obviously if you try to do TLD in real life you will probably die. We all read the disclaimer. What do you reckon the biggest gap between the game and reality is?

• climbing a rope with 44.9kg of gear on your back
• you can just skin animals effortlessly
• cooking rotten meat makes it safe
• you can cure animal hides by leaving them on the floor
• coal respawns
