Millennials may be doomed to look older than their years if they keep using technology as they do.

As a person's posture gets worse their upper back muscles stretch out and the neck creeps forward, this makes the head weigh at least ten pounds more than it should. In turn, it causes structural back problems, and in extreme cases it can even cause breathing problems.
