For example, the skin on our back is subjected to more physical stress and exertion than our fingertips. Because of this, the skin on our back is thicker, giving the tissues underneath it greater protection from mechanical damage such as cuts and bruises. Meanwhile, the skin on our fingertips tends to be thinner, allowing them greater sensitivity to perform tasks requiring delicacy and agility. This greater sensitivity also helps protect our fingers from dangers our backs are not as likely to face, such as touching a hot stove.
