During their first excursion into the forest with Sara, Aiden & Michi remove a decaying dead body hanging from a tree. As Michi cuts the rope, Aiden takes the body in a "Fireman's Carry" across his shoulders and lowers it to the ground.
The chances of this happening in real life are extremely unlikely. Even an inexperienced person like Aiden would know better than to make close, direct physical contact with a putrefying corpse, which is undoubtedly swarming with bacteria and insects- as well as leaking any number of bacteria laden bodily fluids- creating a highly unsanitary situation.
Furthermore- immediately after having the corpse directly across his shoulders- Aiden continues his hike in close proximity to his companions. Not only does his light color T-Shirt show no sign of bodily fluids or rotting flesh, in real life the smell of the decaying body on Aiden's clothing and skin would be so overwhelming as to be unbearable, not only to him but to those around him (that's why those who work around crime scenes, dead bodies, etc., wear special disposable bio suits and sometimes must even dispose of their street clothing if it is saturated with the odor of decaying tissue- the smell is that bad).
