At 93 years old, Lewis Taub is not your typical college student.

"I started taking auditing classes at Saratoga Springs in 1994," Taub said.

Since then, he has never looked back.

"One course every semester for the last 25 years," Taub said.

Taub has attended more than 50 courses at Skidmore College, from history to religious studies.

"When I go to class, I feel young," Taub said.

His thirst for knowledge has made him pretty popular around campus. Classmate Nick Leonard says it is refreshing to see.

"Lewis comes walking in, who is not 19 or 20 years old. I think it’s a really great reminder that you’re never done," Leonard said.

The retired optometrist previously held two formal degrees before he enrolled at the age of 68. He was motivated by his late wife, who re-ignited his passion for learning.

"My wife is so smart and has such a good education, and I felt a little inferior to her," Taub said.

Even with an honorary degree awarded to him by the college, the lifelong learner says he has no plans of slowing down.

"As long as I'm alive and my brain still functions, I will take a class every semester," Taub said.
