From wikipedia: " The human earlobe is composed of tough areolar and adipose connective tissues, lacking the firmness and elasticity of the rest of the pinna (the outer edge of the ear). Since the earlobe does not contain cartilage it has a large blood supply and may help to warm the ears and maintain balance. However, earlobes are not generally considered to have any major biological function. The earlobe contains many nerve endings, and for some people is an erogenous zone.
Earlobes are normally smooth, but occasionally exhibit creases. Creased earlobes are sometimes associated with genetic disorders in children, including Beckwith-Wiedemann syndrome. In some early studies, earlobe creases were alleged to be associated with an increased risk of heart attack and coronary heart disease; however, more recent studies have concluded that since earlobes become more creased with age, and older people are more likely to experience heart disease than younger people, age may account for the findings linking heart attack to earlobe creases. The earlobe crease is also called Frank's Sign. "
For your earrings of course . .pierced or clip on . .dont ever let your kids do the stupid disgusting thing of putting in these things that stretches the ear like Natives do . It's so bad and don't think it grows back. How would they find a job looking like U-Bangis . .creepy
Yes there are a few good uses for earlobes. You can mount earrings on them and they look better than rings or beads on your nose would. You can stretch them, they will flap against your head when you let them go. Also you can flip them in tune with your favorite song.
