Here's something people might care about: your smartphone might give your neck and lower face a crease. While that can't be worse than eye cancer and brain tumor, vanity will make stop you in your tracks from smartphone over-usage for sure.

And the worst part, you're probably not going to do anything to stop it.

The "tech-neck" affects mostly people between ages of 18-39.

Research say that this group peers down to look at their phones at least 150 times a day.

From The Telegraph:

Dr Christopher Rowland Payne, Consultant Dermatologist at The London Clinic, said: "The problem of wrinkles and sagging of the jowls and neck used to begin in late middle age but, in the last 10 years, because of 'tech-neck', it has become a problem for a generation of younger women."

A constant downward gaze also contributes to further lines and creases around the chin and neck area, according to skin experts.

"Neck skin is exposed to sun every day because of low necklines, especially in women, but people are less inclined to think of protecting their necks than their faces," Dr Rowland Payne.

"This is bad news for neck skin as it starts off finer and sun thins it further. Finer skin wrinkles more readily and the fat of the neck may sag."

Neck and lower face crease sounds ugly doesn't it. None of that here though:
