For over 100 years scientists have believed that the purpose of fingerprints is to help us grip objects. Researchers have now discovered that fingerprints do not improve grip at all. In fact, fingerprints actually reduce friction and our ability to grasp smooth objects. So why do we have them?
By measuring brain wave activity in sleeping adults, researchers have determined why gently swinging makes us fall asleep faster and promotes a deeper sleep. Rocking actually helps the brain stop processing and may improve memory and repair mechanisms too!
