You already know that some species of reptiles shed their skin, but did you know, humans do too?Well not as dramatically, but without knowing, humans shed about 600,000 particles of skin every hour. That works out to about 1.5 pounds each year, so the average person will lose around 105 pounds of skin by age 70. Kind of creepy isnt it?

The human heart is remarkable, did you know, Your heart can keep beating even if it is separated from the body because it has its own electrical impulse? And that every day, your heart creates enough energy to drive a truck for 20 miles (32 km)? You need to take care of it though.
