91-year-old calculus teacher connects with students using tried and true old-school methods
"If I had a wife, she'd probably leave me within a week. I mean I'm sitting there working all night trying to grade papers. Don't have time to run around."

91-year-old teacher is using his knowledge to connect with students.
There are some people who work well beyond retirement simply because they enjoy working. While many people look forward to retiring, not everyone is content sitting at home or spending much time traveling around the world. In fact, my own grandfather was one of those people who worked beyond retirement, ran five miles a day and boxed until he was well into his 70s.
But Lou Kokonis has surpassed people working into their 70s and even 80s. Kokonis is 91 and still working at the same high school in Virginia that he's been teaching at since 1959. We're not talking about coming in for an hour or so a day to teach a class and then going home to nap. The math teacher has a full class load, rolling in every morning before most other teachers arrive and staying up into the night to grade assignments.
Kokonis is the real deal, and while his handwriting may be a little shakier, his mind is still as sharp as ever. What's even more remarkable than his continuing to work into his 90s is the fact that he's able to build genuine connections with his students regardless of the multigenerational age gap.
Mr. Kokonis told CBS Mornings that he believes he is able to reach his students because he still offers free Saturday tutoring just like he always did. Turns out, his early arrivals and work on Saturdays are what helps keeps his students engaged, though he admitted cell phones are a challenge.
Of course, in the late 1950s, he didn't have to compete with cell phones or learn to use computers or Promethean boards, but then again, we also didn't have 50 states. In his 60-plus years of teaching, he has been a witness to ever-advancing technology in the classroom firsthand.
"To be working and teaching this long and to still like put in all this extra effort on Saturdays, I really admire that about him," Mohamed Eltireke, a student at the high school, told CBS Mornings.
At a time when there's a national teacher shortage, Mr. Kokonis is filling a vital role, and while one of the students he taught has already become a teacher and retired himself, Kokonis has no plans to do the same. He plans to finish out the year and says, "My mind is set that I'm going to do well this year and I'm going to enjoy it, and I'm going to try to come next year if they'll take me."

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.
