ST. LOUIS, MO (KTVI) - Ladies and gentlemen, the latest in human evolution: "swiper's thumb." Seriously. It's when thumbs get bigger from constantly swiping the screen of your smartphone.

Dr. Richard Lehman M.D. explains the newest result of using smartphones, and it affects almost all of us. He says, every one in eight people between the ages of 18 and 34 notice a difference in their hands.

Research shows 30% of smartphone users have begun to see physical changes in their hands, some even noticing growth up to 15%, the muscles slightly bulkier from all that swiping.

Young adults aged 18-34 have notices the most changes, with one in eight developing deformity as a result of continuous tapping and grappling with large handsets.

Increased thumb activity has been causing the muscles in human thumbs to grow about 15 percent larger.

Fortunately, the pros are predicting voice technology will interfere, before human bodies are changed forever.

Siri, we're relying on you!
