Separated at birth?
On the left is Steven E. Feldon, M.D., neuro-ophthalmologist extraodinaire (among other areas of expertise, he specializes in Graves' Disease and related thyroid ophthalmopathy, who authored the textbooks concerning thyroid ophthalmopathy being used in medical schools today) and holder of additional degrees including an MBA. Dr. Feldon invents ophtalmic equipment and devices (if you've had your eye opressure checked recently, chances are that it was done with the use of a device invented by Dr. Feldon) in his spare time when not conducting his duties as Director of the Bausch and Lomb Department of Ophthalmology at the University of Rochester School of Medicine.
On the right is Thomas S. Monson, Grand Pooh Bah (or Presdeint and Prophet, Seer, and Revelator) of the Church of Jesus Christ of Latter-Day Saints.
To be fair, I believe Dr. Feldon is more than a few years younger than [President] Monson.
