221B methodology

• You can tell someone is a PC gamer if they automatically rest their left hand over the WASD keys. You can also tell by how frustrated they get when even a minimal amount of lag occurs.
• If someone has bruises on the inner side of either arm, particularly females, they may be archers and the bruises are left by the string when the arrow is loosed.
• Bruises above the knees can indicate rock climbing – from hitting your knees on the grasps. This is more common among amateurs and less common among experienced climbers.
• If someone often touches the bridge of their nose or near their eyes, they are most likely used to wearing glasses and are habitually going to push them up.
• You can tell if a person is right-handed or left-handed by the length of his/her fingers. The bones in his/her dominant hand will be slightly longer.
• A way of spotting a (practicing) gymnast is to see if the balls of their hands are red, calloused or peeling. There may be traces of chalk on them too, as it is sometimes hard to wash off.
• You can tell if someone is a swimmer by the skin around their eyes and hairline. It usually is very dry – the swim cap and the goggles can cause the dryness. They also may have dark rings around their eyes.
• If a person has colour themed or coordinated clothes, any aspect of appearance that doesn’t match is suspicious.
• Scratches on a lock mean that the person was shaking when using the key: fear or the cold would cause lots of small scrapes, while drunkenness would give long, deep scratches.
• A person usually makes a lot of gestures when telling a true story; when telling a lie a person’s hands will stay noticeably still.
