How high is it safe to cliff jump?
This, of course, varies depending on the height you are jumping from. But in general, you should look for something around 7 meters or deeper. This will be enough for pretty much any jump. If you are jumping heights of 25-meter plus, 10 meters plus is a good depth for a safe entry.

Why do scuba divers wear special suits?

Hence, the deep sea divers wear special suits which protect them from extreme pressure of water. These suits are called diving suits.
Can sharks smell my period?

Why do divers wear black?
Black is the first color to absorb photons, which is responsible for the UV resistant properties of your wetsuit and aids in the absorption of heat. With the water trapped, you want all the thermal support you can get. Carbon black added to raw neoprene supplies exactly that in terms of both heat and structure.
Can sharks sense fear in humans?
Can Sharks Smell Fear? No, they can’t. The sense of smell of a shark is strong, and they can smell everything that interacts with their sensory cell on their nares, but this doesn’t include feelings such as fear. But you need to remember that sharks don’t rely only on just their sense of smell.
