A 100-year-old neurologist who's still working shares his secrets to longevity
Guinness World Records named him 'world's oldest practicing doctor.'

Dr. Howard Tucker from St. Vincent Charity Medical Center.
Dr. Howard Tucker added another honor to his illustrious career last year when the Guinness Book of World Records named him the world’s oldest practicing doctor. At the time, the neurologist was 99 years old and still seeing patients.
Now, at the age of 100, he told TODAY he recently stopped seeing patients but keeps himself busy teaching medical residents at St. Vincent Charity Medical Center in Cleveland, Ohio, twice a week.
Dr. Tucker believes his long career is a major reason for his incredible longevity. “I look upon retirement as the enemy of longevity,” Tucker told TODAY.
The doctor was born in 1922, graduated from The Ohio State University College of Medicine in 1947 and served as a Navy neurologist during the Korean War. “Anyone who was discharged from the Navy for neurological reasons, if his residence was east of the Mississippi, I had to examine him before he could be discharged,” Tucker told the Jewish Telegraphic Agency.
Dr. Tucker practiced neurology at a time when CT scans and MRIs didn’t exist, so diagnosed his patients using little more than his knowledge of medicine.
“We used to have to really think through a problem because there weren’t any diagnostic tools of that magnitude,” Tucker told JTA. “We used to agonize over a problem. Is this a pattern of a tumor? Is this a pattern of abnormality with a stroke? In those days we had to work harder, but it was fun.”
It’s no surprise that, as a neurologist, he believes keeping mentally active is the secret to a long life. He told News 5 Cleveland that he tries to learn something new every day with a focus on new advancements in the medical field.
He stresses the fact that people should remain active as they age, whether that means staying in their careers or engaging in mentally challenging hobbies.
“I think that to retire, one can face potential shriveling up and ending in a nursing home. It’s fun staying alive and working," he told TODAY. “It’s delightful work. Every day I learn something new.
“I’m going to caution (people): If they retire from their work, they should at least do something as a hobby, whether it be communal work or self-hobbies,” he continued, “you need a stimulus for the brain daily.”
Dr. Tucker clearly knows what he’s talking about both as a centenarian and a medical professional. A 2016 study of 3,000 adults published in the Journal of Epidemiology and Community Health found that staying at work for an extra year reduced the risk of dying from any cause by 11%, over the following 20 years.
"Retiring earlier would seem healthy because you might escape a stressful workplace or have more time to exercise—a few studies have shown this," CBC longevity columnist Sharon Basaraba said. "But more and larger studies have concluded that early retirement is actually a risk factor for early death."
Dr. Tucker attributes his longevity partially to his genetics because his mother lived to be 84 and his father, 96. But lifestyle habits are important, too. “Everything in moderation, except no cigarette smoking—that’s about it,” he told TODAY.
He also has a philosophy he lives by.
"Study each day as if you were to live forever, and live each day as if you were to die tomorrow," he told WKYC. "I've carried that with me all the time."

An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
“But the REAL question is: do you now have X-Ray vision?”
“You can just say you're a superhero.”
“I would make a few stops on the way home just to freak some people out!”
“I would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.”
“This one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.”
“I would save those for fancy special occasions! WOW!”
“Every time I'd stop I'd turn slowly and stare at the person in the car next to me.”
“Keep them. Tell people what to do. They’ll do your bidding.”
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
