The next time someone complains that you never put down your iPhone, you'll have a great excuse: Your iPhone may help you live longer.

Health insurance provider Humana has launched an iPhone app to promote health and well-being through gaming.

Colorfall, available at the iPhone store for $2.99, is a puzzle game designed to exercise cognitive and physical skills. Players earn points though puzzles and photo challenges that keep the mind and body moving.

This is the first in a series of games to be released by Humana designed to encourage healthy behaviors.
