According to Lior Shamir, a professor of computer science at Lawrence Tech University, people’s knees are as unique as our fingerprints or eyes, NBC News reported.
“I used to work on genetics [research] and with genetics you start thinking about what makes people different,” he told the news outlet. “[This could be] something, like a fingerprint and iris, [that] is so different—our external as well as our internal [traits are unique].”
