Darrick E. Antell, MD is world renowned for his research of identical twins. 
The inspiration for his study came when a patient asked: “how long will my
facelift last?”. Dr. Antell replied that the proper answer to her question would
be forever, but prefaced that if she had an identical twin who did not have a
facelift, she’d always look younger than her twin.  Although both of them
would continue to age, the twin without the facelift will be visibly older. For
