If you were of the opinion that it was just snakes that shed their skin, then think again. Instead, we humans are right up there with the best when it comes to getting rid of our skin, as it is believed that the human being will completely change the outer layer of their skin every second month.
In order to achieve this, we have to shed in the region of 40 pounds of skin, and you can just imagine where all of that ends up going on a daily basis. Also, this is something that we continue to do throughout our lives, so you have a lot of shedding to do and a lot of new skin to grow before your time is up.
