According to an old English proverb “Necessity is the mother of invention” and for Dr. Jerry Tennant, this has proven to be true. A practicing Ophthalmologist with a thriving clinic, Dr. Tennant was forced to close his office in 1995 after contracting three different viruses that settled in his brain. In just a short amount of time, Dr. Tennant had gone from being a vibrant doctor researching and developing laser surgery and ophthalmic plastic/reconstructive surgery, to a very tired and ill man who required 16 hours of sleep a day just to survive.
