Crocodiles can sprint surprisingly fast on land 🐊, but they struggle with sharp turns, which is why zigzagging might just save your life. 🏃‍♂️💨

These prehistoric predators can reach speeds of up to **10–12 miles per hour (16–19 km/h)** in short bursts, using their powerful tails and muscular legs to lunge forward with terrifying speed. However, their bodies are built for straight-line ambushes, not agility, meaning a quick-thinking human who runs in a zigzag pattern can often throw them off course. Wildlife experts note that while crocs are formidable hunters in water, they tire quickly on land and rarely sustain a chase for long.

Still, your best defense isn’t to test your zigzag sprint, it’s to **stay well away from the water’s edge**, where crocodiles strike with lightning-fast precision. These ancient reptiles have survived millions of years for a reason, but knowing their limits might just keep you among the living. 🌿

What is special about elbow skin
The skin on your elbows is special in several ways:

1. *Thicker skin*: The skin on your elbows is thicker than on other parts of your body. This is because it needs to withstand friction
2. *More folds*: Elbow skin has more folds than other areas, which allows it to stretch and move when you bend or straighten your arm.
3. *Less hair*: Elbow skin typically has less hair than other parts of your body, which may be due to the constant friction and pressure.
4. *Unique structure*: The skin on your elbows has a unique structure, with a higher concentration of collagen and elastin fibers. These fibers help give the skin its strength, elasticity and flexibility.
5. *Dryness*: Elbow skin tends to be drier than other areas due to the constant bending and stretching.

Overall, the skin on your elbows is adapted to withstand the stresses and strains of daily life, making it a remarkable and resilient part of your body!
