Biology fascinates Alicia Keys

London: Singer Alicia Keys has developed new obsession with biology ever since she has given birth to her first son Egypt.

The "Try Sleeping With A Broken Heart" hitmaker can`t stop staring at the baby because she has become fascinated with the human body, reports femalefirst.com. "I am most enamoured with anatomy at this point. The miracle of the human body. The ability to create all these small amazing machines of veins, capillaries, digestive systems, eyes, ears and nose," Keys wrote on her blog. "Never have I felt such disbelief, such awe, humility, godliness, such strength, power and possibility," she added. IANS
